Level 59 is actually the last level (level 60 is just autoplay). For those who struggling with level 59, do your best to beat it and you'll get the ending!
Level 2 can be 100% cleared in 1 slice. Cut out 2 VERY thin (2~3 pixels) rectangular pieces from the bottom of the top 2 boxes, they'll start shaking and eventually fall. Ignore the fail notice (do not restart) when boxes are still shaking! If boxes stop shaking, restart.
(TESTING: Tasselfoot) This guy should be fired. I just wanna ask you, Tasselfoot. Have you ever actually tested the game? Bugs everywhere, it just seems like a beta version.
My strategy: When there's no rival nerve, go with a moderate speed so you can collect powerups to warp(yellow/green) or make next rival easy to deal with(purple/teal). When you meet the rival, Go fast from the side to pass them. Try not go through rivals as they will easily block your way. At some place(around 30000μm, 60000μm, etc) the proteins are scattered quite thin, makes avoiding rivals difficult. So you may need some luck too.
