Game play was rather short. I thought I might need to solve the maths, but I didn't and escape through a vent.

Hey, Great game! I think it's really good for your second game! You should keep making these interesting minimalistic games. Maybe the next game should be longer and have more sounds in it. But overall, it's a great, simple game!

I think people are being way too negative.
It's a great game and there are NO designers, it was developed by a programmer alone.
The game was great, got me stuck on what to do with the 3 0 4 (tip: try sliding) and I really liked it!
I just thought it was kind of short but maybe that's because I play way too many of these games.
Next time, for better rep since it apparently is THAT important, see if you can find a game designer in the forums ;D

I see great potential but some things were a bit confusing. When I went through the first door with the pass code it looked like I just ended up back where i started and I could do it again? Is this supposed to happen? The art style could have been better but hey this is far better than anything I could do I have absolutely no Idea how to make games, so well done. It gave me a bit of a submachine feel. I like weird or unusual games like these. I didn't really get the ending though, I escaped through the vent? I wanted to look around more though :( Oh well. 4/5 great effort, well thought game.

Don't listen to all the reviews i think this game is one of my most favourite escape game. At first when i saw the paint style in the first room i thought that this game is going to be one of those easy peasy games but then you find out that it's meant to look like that.
