I felt kinda dizzy after playing it, not gonna lie. :D
But this camera angle is is also its strength and very creative. I also had the problem with the ui when trying to play it in the browser. Once I had it fullscreen everything worked as expected.
I liek the character and the animation. Everything feels a little janky but somehow it fits together.
I also encountered some hitbox issues when doing a jumping puzzle. Even tho the character was very responsive I hit the ceiling which made the jumps harder then they should be. (I think it was the 3rd level or so)
But a good game non the less!
