This is really well-polished and the art and sound design come together nicely. The mechanics are explained and tutorialized in a nice way, and the environments feel engaging.
I think this has the potential to be really fun and would maybe work really well for someone better at this kind of game than I am - though I can't entirely tell if it's me or if the controls are a _bit_ clunky - I feel that sometimes being killed by a waterfall at the edge of a platform you're supposed to be on can be a bit punishing, and sometimes felt like a jump I thought should register didn't - maybe for lack of enough coyote timing.
By far the mechanic I struggled with the most was the shoot-jump with space and right mouse. I could not consistently get that to work at all, so maybe I was missing the exact sequence required here, but wish some of the button combinations had been a bit more generous with me. I tried to get past the waterfall section many times but ultimately couldn't hack it without getting frustrated because when I thought I'd be doing a high jump I'd instead get nothing to work and landed in the water too many times.
