No idea how the lizard stuff works, no patience to make sense of it. Unskippable win/fail screens are not fun, as is having to slog through obnoxiously easy puzzles just to get another example of an inscrutable one, and then having the game taunt me for not getting it.
Thanks for the feedback -- I agree it's really unfun when you're stuck on one type of puzzle, to not have an opportunity to practice it again until solving 5-6 puzzles you already understand.
I'm brainstorming some ways to address this as I stretch this into a bigger game, like having different sections which focus on specific puzzles. I think playing the same exact puzzle over and over is slightly too repetitive, but maybe something having it be about 40% would be OK.
