Another Godot user, nice! Really nice game: polished, sprites are cute, great concept and base mechanics, as someone already said controls can feel a bit slippery/floaty but I got used to them pretty quick, I really like the color palette and the geometric/minimalistic background that fits very well with the music, the parallax background and it runs smooth!
I playtested for a little bit (to find something that could be useful for you) this is what I noticed (maybe you already know about them):
- you are on a moving platform and you are not moving concerning the moving platform, you shrunk -> (probably because of the different inertia you gave to big and small states) you are thrown forward (in the direction of the platform movement), I would expect that if I'm I got zero momentum respect something shrinking does not change that
- I was able to do the following (I think it could break some levels, for example, I used it in level 2) a combination of jump and un-shrunk in constrained space:
Anyways, super great job, really enjoyed it!
