CLIMB UP!! is an NES game written in 6502 assembly. The web link allows you to play it in your browser (and edit the source code!), but for best effect, download the ROM image and play it in a local emulator. <del>The web-based emulator's sound isn't working for some reason, but I'm still working on that</del> the web-based emulator's sound works sometimes on some Chrome browsers. Click the megaphone button to see if it works for you.

To move your guy, use the left/right button. To jump press the NES A button (mapped to 'X' key in the browser version)

You wrote this in 6502 assembly? That is insane and awesome.

This game is really cool, but just my two cents, I would have liked a button that kills your guy, so if I miss a jump, I don't have to just wait for him to die.

It's pretty cool and the fact you wrote it in 6502 assembly is crazy.

That was pretty fun.
And you wrote it in under 6 hours, right?

This was so fun! Nice level design, controls were a little... twitchy.

@awenonian: Yeah, a few of my friends said the same thing. That feature wasn't really something I considered until I actually made the levels. :)

@megashroom: I think I spent about 14 hours altogether at the computer.

@slat: Yeah, if I had more time, I would have tried to make it so you didn't need frame-perfect timing to play. :)

I wish there was a button to kill your guy before 10 seconds :)

Its been a long time since I wrote assembly language so looking at your source code brought back fond memories. I just played the web version so had to leave the sound category blank. Interesting concept though the thought of climbing on the backs of your dead failures could be considered disturbing. Great entry.

Great concept and coding it in NES assembly is an incredible feat. Only issue I had with the game is that the size of the jumps seemed random and things moved too quickly and finicky.

Very cool. Jumps need some "hang time" though probably.

That's great seeing new games being made with older materials. This actually makes me want to program in assembly again!

The puzzles aren't that difficult, but it can have the potential to have good puzzles.
I wish it had a "skip the whole 10 seconds" button, to make the game faster. Also a restart button. Map it to either B or SELECT.
For some reason, the game is buggy in Nestopia. Works fine on FCEUX.

I still can't believe someone would be able to make a game on assembly. On a Ludum Dare compo.

It's crazy that you wrote that in 6502 assembly, and it's admirable, that you made a game for SNES - I also like how you connected the other theme, death is useful ;)

You fantastic son of a bitch. All it needs is a countdown timer! Great job!

6502 assembly... You are insane! :)

I love the idea, really adictive.
I had fun time playing your game!

A countdown timer would make a nice addition

Very interesting Game :) The fact that it's written in 6502 assembly makes it really unique and awesome

That you wrote this in Assembly is insane!

The Theme seems to hold back the game play, the time trial-ing is fun but coupled with that is waiting in a pit for 10 seconds. That being said, it was still easily fun to play until the end, I enjoyed this game. All that's really missing a suicide or next guy button, though I understand that would have diminished the theme.

And of course, wow, 6502 assembly. Yeah, have some stars. That you built it in assembly is cool, but that it was still genuinely fun, pretty and innovative just makes it brilliant.

very nice little game.

I could not rate the audio (shame on me, I do not have a NES emulator on this PC), but the game (and the way you made it) was awesome !
(on a totally unrelated topic, we interpreted the theme in a very similar way. But doing it in Java is not as cool as doing a NES game)

Man, 6502 assembly! :O

Cool! Didn't know about #8bitmooc, that's pretty cool to do Ludum in. The game itself felt a bit too fast @ 60 fps, but still fun to play (60 fps made it challenging)

Lancey says ...

A good idea, and spectacular that you wrote it in assembly. The theme works against the game though. If you keep developing this, definitely try to tighten the controls a bit!

mutuware says ...
Aug 26, 2013 @ 8:12pm

I'll just browse the source. Uh..uhuh. Yep, makes no sense :D
It's fun to play. Mad props!

Aug 26, 2013 @ 9:50pm

Maaan, I'll rate it high just because it's written in bloody assembly in 48 hours!! :)

Great job creating an actual nes game. That couldn't have been easy. Love the concept too.

Unfortunately the NES version wouldn't run right in Nestopia for me. Web version works okay but it felt like it takes way longer than 10 sec to die (a die button would have been handy). Overall this is an awesomely ambitious entry and the general concept could definitely be expanded into something cool!

Tested it on a couple of emulators but it didn't work well. It was laggy, crashed a few times and the sprites blinked a lot. Worked well on chrome

This must have been hard to make! And yet the game design is great and it's fun. Awesome work. There was of rare bug where I could go through some wall, but I figured assembly language would be extremely difficult to debug.

As a non-technical dude I didn't really care about what it was made with, and I honestly wasn't expecting much... but somehow I really really really dig this thing, it just clicks for me.

Good that you made a "Web" version of it. Not much of an innovation here, but no bugs, and looks cool.

Aug 28, 2013 @ 1:06pm

Nes-Game? Awesome!

Nice! It's good to see that 8bitmooc works.

When I jump and hit a platform from below it sticks until I release the jump button. In this state I can not move but if I stuck on a previous entity then they can move together. I don't know if it's a bug or not but it's wierd.

For best results, provide a Web version of your game, or a Windows version with no dependencies. Also be sure to rate about 20 games to improve your visibility.

MY GAME DOESN’T SHOW UP: If you can’t find your game, it’s usually because the URL to your downloads are missing ‘http://‘. Fix your URLs ( and you will show up.

MY GAME CRASHES, IS UNBEATABLE, OR I MADE A TYPO: We allow you to fix crash or win condition bugs after the deadline (in a sense, like “porting” to support more players). We also allow “typo” bugs. I.e. A true that should have been a false, a word that should have been a different word, very tiny changes that you would have caught if you had more sleep. We leave this open to interpretation, but generally speaking your game should be identical to the game you submitted. No new features, just things you messed up last minute. Typos.
