Not sure how you were able to continue playing after a game over, nor why it would crash on the 4th planet. This version seems broken as hell lmao. Do you mind sharing more details on the crash? What was happening when it occurred?
Appreciate the feedback on the difficulty and the SFX (or lack thereof). Wondering if the values should be tweaked down a bit, since it's not supposed to be super-hard on the first few planets.
