Firstly, I adore the art style of this game just at a first look, it's very cute.
A couple issues though:
None of the main controls (dash, roll) seem to do anything, and you don't seem to take damage. Also, there's no indicator of movement (no texture in the ground) so I was very confused for the first few seconds.
I really wish I could see what interesting rolling mechanics you had thought up, but I can't seem to get them to work!
If you fix some things and make a new version, I'll definitely check it out!
