Let me start off by saying I like your characters and vibe. I'd like to leave some feedback.
Some of my feedback has already been listed before. The dialogue sound in particular is grating and the game music is very repetitive.
One thing that really bothered me over anything else is how the camera moves. With how quickly the character falls (it feels like they have lead in their boots or something the way gravity pulls them) and how the camera follows them exactly it made me a little motion sick. Not everyone suffers from that (I don't have it too bad either luckily) so it may not be a huge deal, but something I wish was addressed for my own comfort. I recommend looking into how other 2d platformers tackle their camera movement. Plenty of resources on this out there on YouTube for example!
Still, nice little game. Keep it up!
