I really like this 'lii game, I find it far more approachable than even the main game itself! One small problem though, I seem to have bugged it out. After selecting all the upgrades and unlocking all the weapons, I swapped out a couple of weapons and quickly selected play - and now I'm frozen. I can turn to move, but can't actually move at all, and the screen seems stuck in the top left of the play window. The electricity isn't even animated, so something is definitely off.
