This is cool! I really like the player movement, it feels smooth and the animation adds a lot of charm! I think this game could benefit from a larger camera lens and smaller map sizes. The levels are quite large and the camera is very zoomed in, and along with the fast movement speed, I tend to lose my bearings in the levels. We also start off without knowing where the end goal is, so there ends up being a good amount of just running around hoping to find it. I think these issues could be fixed with smaller levels and a larger camera lens since that way we could see a larger percentage of the level at once, making it easier to traverse and figure out where I should be going.
The boss was also quite challenging, I think it jumped around too much in I think phase 2 (below 50%)? So I could never get a jump on top of it, even when trying to time my jumps when the boss lands. Maybe also reducing the boss size to make it more fair with how high the player jumps?
Otherwise, I really like the idea of being able to change the camera perspective to walk on walls and such! It was executed well and I had a fun time!
