Nice game, great sprites and fun gameplay. I liked all the different weapons, my weapon of choice is the spraying one, because it autofires and I can use it to snipe enemies from outside their range. Speaking of enemies, AI can be pretty nasty to deal with, they are very quick at shooting back and the only answer is jumping over bullets. Maybe adding a crouching action could be nice, so that one can duck from bullets or snipe enemies from advantaged positions.
Great entry, congrats and well done!
