So I enjoyed this game and think it has a great unique creative mechanic. However, I would've personally put at least 1 more level between 2 and 3. You can pretty much pass through level 2 without even paying attention to the mechanic at all, while level 3 forces you to learn it, solve a puzzle, and do some tricky platforming all at the same time. The first few minutes of a game are essential after all, especially when game jam players have the attention span of toddlers with the amount of games they can play.
