Ok nice concept with a strong VVVVVV vibe. Like the cinematic also, really convey the story/feeling with minimalist artstyle. On the technical part, there is room for improv:
- when falling, getting close to a wall stop the fall, i'm assuming you put vertical velocity to zero everytime you collide? maybe you should just check for ground only.
- You should make a animation or a small coroutine to inverse the screen, it becomes really confusing to know which is where if you just swap
- Remove the tutorial everytime you fail level 1, it's kind of frustrating
