You already know your game is full of GMI energy. I have only one objective complaint, the key bindings are not localised. It will not always be "keys on bottom left of keyboard" – on non-english layouts the keys start being all over the place. I think all input libraries have some abstraction to fix this easily, e.g. in SDL it’s KeyCode vs. ScanCode.
Subjectively I am not excited for the mix of puzzling+execution, I mean the execution is really not hard, but it sucks having to redo a level from beginning, when I had the right plan, just because I didn’t line up the tongue handling correctly. There were a few situations where fairy hitboxes behaved unexpectedly. But maybe all this is more fun with the proper key layout.
Cheers, and good luck!
