It feels like a rather early version, perhaps a prototype.
The "about" and "how to play" buttons don't work, I actually didn't understand what I'm supposed to do in-game, I tried to figure it out for about 2 minutes and then exited the game.
The game seems to not have sound whatsoever. It's probably a good idea to add some sound, as it will certainly enrich the game.
If you can explain to me what I'm supposed to do in-game, I'd like to give it another go :)
