cant wait for the artwork updaaateee!!
Got few things to suggest fixing/improving (you probably know these things already and im stating the obvious again lol)
1. The sound doesn't loop while on same stage if youre slow like me:P (noted in stage 2)
2. The pink guy is impossible! (stage 2 in between the two moving platforms [might be just me though:P ])
3. im on 1680x1050 on chrome and on fullscreen i see the ends of tree images and white space on top and bottom
4. when enemies die or you die, enemy "bullets" still fly on their course where it would make more sense to me personally for them to get destroyed.
5. Boss is cool^^ and he deserves a health bar (was i too blind to see it?)
6. that green enemy is a ninja with a minigun!lol i like him:D
I really like it and I'm going to check this post frequently for more updates!
