Looks pretty good, the intro with the thumb joke and Thumb waxing his head so hard he becomes a flaming skeleton made me laugh, but I didn't vibe with the controls.
While I loved the "oomph" the dash has when you hit enemies, a way to cancel the dash or better air control would be really nice, as most of my deaths were from dashing into an enemy and immediately falling into a nearby pit, or bouncing off an enemy that takes more than one hit and dropping into a pit behind me.
