Really like the artstyle! The concept is really interesting and I would have loved if it was expanded upon just a bit more. Could turn out really good with just a little bit more work!!
There are some issues reported in the terminal window, and sadly I could not get past level 2 because of this. 
It appears that the game is having trouble loading the next level.
Some minor flaws, the power-ups need more weight behind them, you barely notice picking them up. I think this could be a great game though!
