In claustrophobic, puzzle-riddled, dangerous mazes, surrounded by countless enemies, you hunt the Evil Masters down with the purpose of eliminating them and the pain they brought. Determination, concentration, and quick reflexes will be your only allies in your desperate quest...


BOH is a dungeon crawler where you need to solve puzzles, collect items, open passages, avoid traps, kill the Evil Masters and the minions they generate endlessly, and ultimately come out of the mazes in one piece. Keep cool, avoid the enemies as much as possible, focus on the labyrinths, and eventually you'll make it to the end.

BOH, thanks to its unique aspect and gameplay, is an immersive experience that makes you feel as if you were actually lost in those treacherous dungeons.

You can play any (unlocked) mission any time, and you can also decide how they look and sound by choosing freely one of the several themes available...

... not to mention that, if you're the creative type, you can even create your own missions and themes (!) thanks to the developer's manual, which provides all the information needed.

In 2009, the original BOH was released first as a professionally produced physical package:

Then, in 2018, to celebrate the 18th and final update, the game earned the ADVANCE tag and received another gorgeous physical release:

BOH ADVANCE was part of the BOH Deluxe package, which wrapped a copy of the former and a copy of the original BOH in an elegant sleeve:

BOH is part of a saga that, as of writing, includes five different games.
BOH opens the story, with the Evil Masters bringing chaos to Earth. Huenison focuses on the fight against one of them, the eponymous character. Eventually the Evil Masters were repelled, but, as seen in QUOD INIT EXIT IIm, during their retreat, Huenison and his companions happened to pass by planet Suinio and decided to cause trouble there as well. In MAH, years later, the danger came from the Apocalypser, the weapon that had been developed against the Evil Masters and that the Purifiers activated to destroy the Earth. Finally, KOG assigns a new task to the hero who turned the Apocalypser off.

I thought I left a comment - it seems I didn't.

Just to let you know I really like your game. I like the camera system, it makes it feel like a first person shooter. The laser to aim is really cool.

I hope you'll make more games like this!

Thanks a lot for sharing such nice thoughts :)
My next games will be totally different (the one being worked on is a multi-level version of QUOD INIT EXIT IIm for the C64), but I have also a 100-mission version of BOH in the plans (it will be free for current customers; several missions are done already).

You're welcome!

Do you have any thoughts about increasing the resolution? Without actually changing,the textures,
just increasing the resolution would still work (instead of using texture interpolation) it'd be very pleasing on the eyes

I don't know how you coded your game so maybe doing this would be too complicated
if you have to change the locations of walls and objects in game, you could simply multiply the coordonates
"x = x * gameScale". So if the new textures are triple in size, x would now be twice as far, keeping the ratio the same. Maybe you wouldn't have to change the levels

Maybe you'd only have to change the rendering - I got no clue I don't know how you made it,
and you're probably a better programmer than I am.

Can't wait to play the new levels

By the way! I tried implementing a similar camera system in a game I'm making, but using a mouse.
It's actually a bit nauseating because with the mouse you can move pretty fast haha
What gave you the idea of using this camera system?

(Edited 3 times)

I'm not sure about what you mean with increasing the resolution without changing the textures, but hopefully this will answer you anyway: the resolution has been chosen to be low because a) it makes it possible to draw (and gives it a meaning) the bitmaps by hand, pixel by pixel (see the developer's manual for the details); b) I like pixels ;)
Also, if you haven't already, please check the dots modes in the options: they allow to change the size of pixels and also the filters applied to them.
(BTW, no, it wouldn't be necessary to touch the missions layouts - if you have a look at the developer's manual, you'll understand why).

New levels: do you mean you have already finished all the 77 levels included in this version?!? :o I see you have bought the game very recently, so that would be quite an achievement! I'd appreciate if you submitted your records to the online standings.

The camera system idea (i.e. the fact that the character is fixed at the center and all the rest rotates around him) came from the coin-op Formula 1 game Tail to Nose (it's mentioned in the TRIVIA section of the user's manual): my teenager mind was blown away when I saw that concept in an arcade in the 90s.
The tile-based lighting idea came from the RPG Shadowlands I saw once on a PC (again in the 90s and again mentioned in the user's manual).
The tile-based field of vision idea came... came... from nowhere, or at least I can't pinpoint any influence (that is, I came up with it myself).

Good luck with your project!

I love pixel art too! What I meant by increasing the resolution, would be to triple the size of the sprites and textures using nearest neighbour (the textures will stay pixely, but when rotated, they would stay sharp instead of needing interpolation). You wouldn't have to redo the art, the art itself would stay at 16px

and no I didn't finish the game yet!. I've done a few levels, didn't have too much time but I do a few of them
throught my day

by the way I invite to check out 'NOXP: Flashlight' that I released here on itch.io, look at the video I put - if you like
the shadows, I could tell you how I did it it's fairly simple. But yeah just increasing the resolution would be great :)

(Edited 2 times)

Ah, I see what you mean about the resolution. Yes, what you suggest is theoretically doable.
This is what happens now: render field at 1x -> rotate enemies -> render sparks -> rotate bitmap -> render main character, aiming tool beam, and HUD -> zoom bitmap (and, at the same time, apply CRT/LCD filters, if needed).
Your idea would need: pre-render zoomed font and main character -> render field at 1x -> render sparks -> rotate and zoom bitmap -> rotate and zoom enemies -> render main character, aiming tool beam, and HUD -> apply CRT/LCD filters, if needed.
The sort of linear interpolation I use can be applied also to your idea without producing blurry results: it would simply smoothen the edges between pixels and it would look great.

I like your idea (and it's really tempting me!), but there are a couple of problems:

  • rendering is 100% software (because I like doing this sort of things and I did not want dependencies on hardware/libraries, especially considering that the game runs on several different systems) and, at the same time, the game is made to run nicely also on 15 year old AmigaOS machines, which thus wouldn't have enough grunt to handle so much data at a decent speed.
  • although the changes aren't too difficult, still it would be a lot of work (relatively) and, unfortunately, I just can't afford it because I'm working on a new version of MAH, I have to release a slightly updated version of Huenison, I have to complete QUOD INIT EXIT IIo (which isn't going to take less than 1 year of hard work), and I'm finishing a short story; on top of that, it's years I've been longing for working on a couple of games for classic Amigas, and I can't wait to do that! (And, on top of everything, let's not forget the demands of real life.)

Therefore, I'm afraid your idea is not going to make it :/ But thanks for suggesting it, it's a nice one!

Enjoy your next missions: as you play them, you'll find more and more surprises.

I've watched the video of your game, and I can see the conceptual similarity to BOH regarding the lighting and field of vision :)
