Thanks a lot!
Happy that you like it :)
I agree with almost everything you said. I limited my work time on this game to just a few hours. Therefore I had to skip the player onboarding completely.
Regarding moving it to level-based puzzles: you've probably noticed that one of the concepts of this game is that each 'round' is created by random. In general, I'm interested in games that use some mechanism to create the content, and less on me creating levels one by one in the editor. My other game, Noisy Space, uses this approach also as well. In Noisy Space, I used procedural generation based on the Perlin Noise function instead of a simple random, so all players get a similar experience without me needing to create many levels.
