Good game but the initial controls are very unclear, which makes the game very unapproachable. E.g. the player needs to magically guess to press escape?!
That's fair, I also mean more generally though. I feel that often Sokpop games however awesome they are you have to infer what the controls are. As someone who'd never played old console games, pressing zxc randomly and it working surprised on occasion until I got used to it. My general preference is that spelling controls out for your grandma is better even if you're not designing a game for your grandma. This is my opinion of course, so up to you. (great game still :D)
