Very cool,
I felt that the player was a bit too heavy on movement/jumps on the platforming levels, and I think the viewport should allow the player to see more platforms at some points.
The beginning is a bit confusing for me😂
as you fall right away then you teleport to the start of the game, and I was trying to figure out if this was all meant to be this way.
So I think a nice transition between different levels/scenes would be nice,
The concept is pretty nice though,
Good Job!
