Simple but promising. I like how closed rooms are dark.

Simple, but fun. Controls make it a bit touchpad-unfriendly, but it's still playable. Would be great if you added sound.

Fun game, interested in playing more when it's finished. Only open rooms visible is a nice feature

I got stuck, I think. Definitely promising. As others have said, the closed rooms being dark thing is nice.

Cool game, you should totally make something more of this!

I liked the idea of the rooms and the doors. :)
The gameplay could've had a little more polish :3

Definitely looks like it's off to an interesting start! I like the way it feels already, so it'd be neat to see it turn into something more. Thanks!

I like the room darkening mechanic, will like to see where you take this

It's hard to play this game with a azerty keyboard, please make available the jump with another key than space !
I don't really understood where I was supposed to go, or what was the goal, but the visibility of the rooms is well done and a really nice feature !

I struggled a bit with the entry but the updated one felt much better! Nice control scheme and like the dark rooms and different properties of the different coloured blocks. Hope you enjoyed getting some sleep!

I forgot to say you're getting extra marks for it being called "!", which is coincidentally the name of an album I thoroughly enjoyed by The Dismemberment Plan

Simple yeat fun. Dark room system is very good idea. Very promising.

AGH I can't believe it's not finished! Looks so promising and plays so well! Please continue, and if you do, drop me a line.
