Thank you for this very complete feedback.
The game clearly need some adjustment. I didn't had time to playtest the game, and realize too late some big issues (like the camera sometimes too high to let the player have a full power range, or the ninja that simply don't stick on the ceiling as it suppose to for some people).
And i'll keep in mind the rest of your feedback for the v2 after the jam :)
For the infinite jumping/rolling animation, I had some issues in the corner, but didn't found a solution during the jam to correct it. I will dig on it !
