Great tutorial! I love that you immediately forced the player to repeatedly use the abilities in order to learn them. The only critique on my side would be that the theme you came up with is more in the lines of 1 2 3, instead of 3 2 1 and the key mappings shown on the UI are a bit counter-intuitive due to their reversed order. It works fine when you get used to it but yeah.
Overall cool idea, the game is very functional and the levels are clever! Good job!
