No bugs that I saw! But why do the levels look different in the screenshots than in the game? Sound would really help this game, also I found myself wanting to fast foreward through the waves pretty quick, so maybe theres needs to be more of a reason to "watch" versus just skipping to the end. Cannons seem a little OP, and snipers seem underpowered. Having multiple paths where you can only "see" parts of them at a time from a different position is cool.
