Pretty much it's for those who got this game: 1) Are any of the tunnels progressable/beatable? I've played them over and over to see if it was a random bug, but the first wall is not breakable. 2) Is the final boss (giant head with the eyeball/brain in the middle) beatable? None of the bullets of mine affect it... 3) Choose game menu, then arcade mode, then any difficulty. When I go past the second stage, it gives me an allocation memory error or something... What's going on?
