Thanks for playing, and also for the comment!
Yeah, there are a bunch of tutorial levels (and I guess that's most of them in this jam version), that effectively were intended to show how each of the abilities work. But forcing you to roll until you get a particular ability runs sort of counter to what the randomness encourages, which is trying to work with what you get. That and it can be kind of annoying when you need to roll over and over again :) I agree that refining the rerolling mechanics and/or ability/level designs to be more open-ended would help.
