That's a touch too hard, which is normal for gamejam games, especially if it's your 4th one. Don't worry, next time try to make it so easy that you could play it with your monitor turned off. It's natural, that when you're making the game it seems very easy cause you've spent time playing with the mechanics already. The non-gameplay aspect is really polished. I like the main menu, the [esc] quit effect and the credits. cool game, although too hard for me which made it not as fun as it could've been.
