This game has lots of potential!
It has a really cozy atmosphere with the art style and music, it's very inviting. My concerns come solely from the mechanics; At first I thought my dash wasn't working, it's unclear that it has to be unlocked. As another user stated, the interact button is "R" instead of "F", leading me to think that the interact button wasn't working. The double jump can be kind of wonky sometimes as far as mobility goes, as it doesn't activate when moving in the air sometimes.
The poison bottle(?) in area 2's interaction either doesn't work, or doesn't easily activate, I didn't know what it was doing there. I got almost all of the little objects in the first area except for the coin, because there was a rock blocking the path (I'm sure there's a puzzle there I'm not understanding...)
Anyway, I like this a lot! Keep it up, and I hope you enjoy Grass Elemental!
