This was pretty solid stuff! Might do with some mouse control in the future. Feels maybe more puzzler than Metroidvania (to me) but the design of the thing is top-notch and it does definitely capture the element of those games with a large portion of exploration and progress being "now how do I get up/over there"?
As others have commented the graphics aren't necessarily the best, but they're serviceable, and the UI that conveys what's possible is fairly straightforward.
