Nice game overall.
I like the crunchy kill sound effects. Makes it pretty satisfying. Although the jump sound effect was a little loud.
The gameplay was satisfying. Hitting those choppers from a distance felt pretty good.
Only really major issue is that the player would sometime get stuck on the wall and wouldn't be able to jump unless you move away from the wall first then attempt to jump. But even with this, the game was enjoyable to play.
