This game is pretty obtuse, but pretty fun despite its simplicity, the fact that you have to exit out to make new towers notwithstanding. I heavily suggest you add more tool-tips (and palette options, and "blast" effects depending on the bullet (or have more than just bullet sprites (custom sprites for statuses, perhaps? Really, like anything.)), as most things are very hard to learn for really no reason (e.g. how tower saving works, what tower properties do, what game modifiers do, and what enemies do). Speaking of confusing mechanics, though, I never got upgrades working, despite my best efforts.
Why are there stocks, by the way?
also the water in the blons map doesn't prevent building 0/10
