Great! The mechanics are really simple to grasp, but very creative. I also like how it gets very challenging. =D

Also, I loved the level transition effect.

Some of the puzzles are pretty fun and the mechanic is really nice.

Thanks for the comments! I wanted to make more levels but my non gamer play tester friends kept telling me it was too hard =D I'll add some beefier ones later.

Nice little one-button platformer. Being able to run up the walls/around the ceiling was cool.

Really addictive, and I loved those level animations.

Mechanics are good, but the challenge ramps up fast. Loved the transition effect.

A one-button-platformer. Nice and on the ceiling too.

Fun game! The transition effect is really well done.

Nice little mechanic! It feels like there's a pretty low margin for error though, even in the early levels.

WE DON'T ALL HAVE REACTION TIMES OF GODS!

[goddamnit]

This is Fun! so good Minimalism!

Great piece of game accessibility with this one-switch game. Fun to play too, well done! :)

Thanks again everyone for your comments and playing my platformer. Since so many people commented on the transition effect I through together a blog post on it.

Any questions please ask me here or tweet @kwrky

Very fun game. I like simple concepts and controls. You got them both =)

Innovative, challenging game!

Seems everyone uses their hardest level as their screenshot, or do I always just give up at that point? Wish the one-button was 'z' or something other than space, I never find the spacebar responsive. That said, loved it until I gave up, well done :)

Oh, and just because everyone is saying it and it's true, great transitions.

Thanks Jimmy, just fyi there are quite a few more levels after the screenshot, and a whole new mechanic =D

I made one small change so now ANY button except Esc is jump

Extra points for wallwalking! Great game, man.

Very nice game, that was worth the time i spend playing on it, will play again!

Veeery smooth gameplay. Good job!

All the praise of the above comments and more! Excellent job.

Very nice game !
The sound got annoying after some time though. xD
Anyway, got 2 or 3 stages past the screenshot. Didn't see the new mechanism. ^^'
Also, as others said, really great transition, loved it!

Mac version is incoming as soon as I figure out packaging, will have to obnoxious and fullscreen until I can rewrite the graphics engine though =/

Truly minimalistic, but really fun nonetheless.

I love the mechanic and the transition thingy. Awesome game!

I don't think you can make a game less minimalist. One key to press, squares and that's it. Great game, the better I've seen in LD#26 so far.

It had an interesting mechanic of gravity, but the actual gameplay I feel escalated difficulty too quickly and a lot of it felt too much like pixel-perfect jumping. Fits well with the theme, but I also feel some more detail and/or audio (music particularly) could add so much, as well as maybe something like a death counter.

Nicely done. I am crap at this game but it is still fun :)

Challenging...very challenging!

AestheticGamer, thanks for your comments. I agree with all of them and I want to do more to fix the issues you've raised. Still kinda recovering from LD but soonish I'll start round 2 of polishing

Simple yet brilliant!
It's really hard and fun, good job!

You do a great job here of gradually introducing ideas, constantly challenging but never overwhelming the player. And what's more, you somehow manage to pull it off with only one key! Incredibly well done.

Quite fun and devious! Simple mechanics but great level design! :) The transition effect was also cool.

very cool experience, loved the perspective and gravity changes

Amazing game i had a lot of fun, love the transitions , and the game play!

Really interesting use of gravity, for me it was alot of trial and error to find the correct jumping points. Sound could have more variation, the level transition is awesome. Well Done =]

Nice level design and interplay between puzzle solving and execution. Fun game, good work!

Very challenging and fun!

Simple, hard, fun! Well done!

Totally addictive. This hits the perfect mark between a frustrating and challenging yet highly rewarding game.

Nice job!
