It's nice to see how much stuff there is to unlock, even if I didn't even reach the second row of unlockables.
It'd be nice if the coins had different symbols for heads/tails rather than slightly darker. It took a while to realise what was what.
Speaking of the coins, although coin flips are supposed to be 50/50, I'm not sure that's the best idea. There were a few rounds where all of my guys AND the enemies coins all landed on tails, even when they flipped, like, four at a time. There's been numerous studies on randomness in games. Maybe put in a little bias towards what players are expecting to get?
