Lovely pixel art and good music. Overall the presentation is very well made, and the dialogue gave me a chuckle. Jumping-wise, it feels very precise, maybe not super enjoyable at the moment given how short your jump is though. I feel like my character arbitrarily stoped before jumping and lostmomentum a few times, that might just be a quirk of the WebGL build. Otherwiser, I don't think I progressed far enough to really appreciate the gameplay!
A few things:
Even though I downloaded the Windows build, deleting and redownloading didn't let me progress to the second level.
In the WebGL build, I can't clear this jump, so I'd appreciate a hint (I'll stop myself from giving a rating for now):
