fun once the yellow tanks kick in, i would make one more type of tank that appears when there would usually be only greens (one that shoots a bit, but not much)
simple is fine and all, but at least give it a background that's not black. parchment or something (or anything) would be better. plus the pure blue buttons are an immediate turn off.
as for the gameplay... looks really good so far, achievements are a nice touch, and i feel somewhat compelled to play on.
i get that its a text rpg, but it should still not be hard to look at...
neat idea, it all seems sort of pointless though, maybe a pause menu with badges.
also, hitting instructions just puts you to the try again screen with a score of Nan...
hmm, decent game, lag was bearable
nice idea with the elements, but imo it clutters things up unnecessarily.
good job though 5/5 (i got just past 2nd boss)
