I made a complete run once again and I'm quite satisfied with the results. I didn't find any game-breaking bug. I like what you did with the Polyps. I managed to do 83% completion in about 3.5 hours. I went into the last zone with all power-ups, 6 energy tanks, but "only" 220 missiles...
Seeing that there are people here asking for help, I suggest we split this thread into two distinct threads: this one for bug reports, and a new one for help and hints on the game. What do you think?
