Played to the game and got to the place with the bat before stopping.
A few notes:
- I like the puzzling aspect of taking over the bodies of others, but some of the razor-thin jumps you have to make are frustrating; especially the very large level with the two rabbits (bottom left and right corner). I'd suggest giving players an opportunity to fix their mistakes, rather than just having to do the entire level over again. In that particular level I don't really see a reason for having the pitfall at the bottom - the platforming is hard enough that adding a pitfall just makes it annoying.
- The movement really needs work. Animations would help inject a little more juice, but jumping and landing particle effects would help a lot; as would a little momentum. Your character also "sticks" to the ceiling when it jumps in low spaces. This is because your y speed keeps increasing even though you aren't moving. Godot has a simple "is_on_ceiling" - set your y_speed to 0 when this happens.
- A menu would do a lot to improving this game - especially providing a "reset" button.
- The Mindhack Gun collisions just do not work. There are many times in which I swore I was hitting an enemy only to watch it go straight through. I'm guessing this is because your "bullet" is just a moving scene, so it's possible to "skip" past the enemy between frames. Fix this by detecting a raycasted space between where the bullet is and where it used to be. Or, just have an "instant" gun with raycasts.
Thank you for the opportunity to play your game. Thanks for sharing!
