Holy crap i JUST lost a match after about 30 matches of just picking random reinforcements/ powerups whenever they came up. I upgraded logically but when the matches came around i just picked random shit and won. It's a nice game, looks great, great ideas, but seriously, i've just been picking random shit all game and i've been winning matches. There's a serious problem here.
This game takes absolutely no skill. Once i realized this i started just choosing the first option that came up (the left most option) when it asks you to choose a reinforcement or a power up. I've won about 20 matches this way, including the boss battles.
