So I get the idea you were trying to have with this game, a hard bullet hell kind of game. The issue is, gamers play games to get a sense of achievement. There is almost no sense of achievement in this game aside from the Kongregate badges. Also, you make this a bullet hell, and we have to be on the pixel to pick up money. Combine this with the fact that we can't replay levels, well we could easily be looking at a player stuck at some level because his weapons are vastly unsuited for this combat, such as those jumping guys, if you dont have enough money and only have straight line fire weapons you're screwed. Also the "bonus" round/time after you complete a mission? That's more of "Now that you beat it survive for a few more seconds and look at the money go away." Should at least make the player invulnerable for those couple seconds. And the "ultimate" 500k weapon? Weak with a long cooldown.
