It really has that "baby's first game" kinda feel... it doesnt really do anything special.... but i like how you see the health by how ripe the peach is, though if that bar wasnt there it would be better. the jumping is tight, but i feel like it would have done better with a little bit of retained momentom. also, the enemies have WAY to much health, with this kind of game, i'd say i 1-3 hits is good... then remove the upgrades if you do that... or make the upgrades do new things to the gun! also, just a general tip,  if you think the dificulty is pretty good, its too hard. (play my 'take care of your pet' game to see an example)
