Negative: The main menu was zoomed in too much on my screen resolution, and the settings button didn't work.
Is it intentional that you have to complete the entire game, each time you want to unlock a level in the play menu. That means playing through the end-credits level at least 15 times.
Positive: The music is well fitting for being on non-stop repeat.
Trying to speed run level 13 and 14 makes for a fun challenge.
Good game with much potential.
