@Sanoke thanks for the feedback. In the android version I have started the game faster but made it speed up at a slower rate. The Clear the Level mode here on the itch.io page has a bug where the bombs sometimes can't be cleared, I'm not sure if I can submit all these updates that I done for the Android release or not. In the later levels of "Clear the Level" mode the Tribbles are supposed to "breed" so fast that it almost plays like the classic game but with breeding instead of a spawn row at the bottom. I think your idea for, no spawning, but you have to be careful about how you remove them is really good! But I'd have to either create each level or come up with some algorhythm so that it didn't create random levels where there was no possible way to win.
