The game is to easy, after just a few levels you can kill all the enemies and get all the money without moving.
due to the limited number of bullets active at one time its not really worth getting all upgrades, screen is full even without the extra guns.
otherwise a fun game.
Yeah, due to the upgrade system your power raises exponentially, while the enemies' stats grow linearly. But because of the engine limitations (could have written a parallel lighter-weight one just for bullets, but meh) you'll max out in power really soon, even before getting all the upgrades (as you've noticed), while the enemies, with an hypothetical exponential growth, would become too strong. Anyway I'm going to try some nice ideas on a less collision-intensive game genre, like a turn-based RPG :D. Thanks for having played my game :)
If you have trouble with the last level you should try to build two Hellfire temples at the two entrances, one on the high ground and one right after it, one of them can kill ninjas in one hit but two of them will help you before its leveled up.
Just build some crypts to deal with everything that gets past them.
As always; save up to a couple of fireballs, you'll need full mana for the big ninja on wave 40.
