I completed the first level 100% and already feel very impressed with what's here!
The controls are pretty solid already, however I feel like walljumping is a bit too easy to abuse with the current leveldesign.
I like the dialogue of the protagonist and like the option to disable it however I suggest adding a third option where the dialogue appears but maybe at a static position where it can't obstruct your view/disorient you, because I do like the writing, it's charming. Removing it altogether would be sad :<
Also regarding the pinball minigame, it's pretty easy and I got it on my second or third try but I would like an option to zoom out the camera to see the entire area, I feel like that could make things even better.
Otherwise I can't really complain. Sure it's simple, but very charming and enjoyable. I especially like the cries of the moles, it totally caught me off guard but I loved it lol
You should make a discord server or something, I feel like this project has a lot of potential!
