Excellent level design, one of the best I've ever seen in a jam! Engaging concept and perfect execution, congrats!!
I'm quite curious about the level design process. You mentioned in a comment that you designed backwards from the solution, maybe you could also comment on how did you choose the mechanics (did you implement any other that didn't make it to the final version?) and how did you go about playtesting to check how hard/easy the puzzles were? Thanks!
PS: it hurts when you don't make it to the leaderboard by just a minute :')
