would you go as far as say you had "Minimal Control" ≽^•⩊•^≼ hehehe
I eventually just lost even though I never let any of the towers run out of paint
oh thats probably why, ur supposed to let some tower run out of paint intentionally, so that a new tower can spawn... thats actually part of the mechanic of the game, u can choose to refill or not, i suggest letting short towers without flags naturally lose paint so that a new better tower can spawn... also towers hitting enemies with similar colors deal critical damage, so ideally u want most if not all ur towers to be the same color
(,,>﹏<,,) hope that helps and u give my game another shot
