Always happy to see other Godot projects! I really enjoyed this game a lot. It was nice and challenging, but ultimately doable. It always felt good getting through a tough sequence.
One issue I had was the end: Once I turned the fans off I headed up, saw a dead end above me, so went back south and through the other off fan. From there I escaped the level into "open ocean", and got lost. It took me a long time to realize you have to bump into the dead end. There's no indication unless I missed something telling you that's what you need to do. It was especially tough to figure out in a game where you spend most of your time purposefully not bumping into things, and by the fact that there seems to be an actual way out to the left.
Overall great entry, keep up the good work!
