Wow, thank you for the wonderful feedback!
The initial screen was a last minute addition and a great reminder to plan for a proper tutorial. Once again I failed to do that. I hope I'll do better one day 😅. Arguably on-screen controls that go away once the player rotates a piece for the first time would probably be enough in this case.
The main jank in the gh version I'm aware of is moving the piece quickly, which feels just terrible. If I were to do a post-jam version, I'd probly revamp the whole drag and drop part of the game incl. rotations. Maybe I'd remove the snapping and just highlight the target hexes instead.
I quite like the multi-hex rotation tween, but I'd a venture a guess it's style over substance and rotating whole pieces would be more readable.
Sorry about the headache-inducing BG. It seemed like a nice touch that the speed would be based on remaining time - shame that I messed it up 😅.
