I like it, especially the sprite work.
I wish there was more in game tutorial-ing for potion crafting, maybe even starting with fewer ingredients to get eased into it. Also, the pop-up text in the first room seemed really sensitive, like you had to be in a really precise location to get it to pop up. I think it'd be better that that space was a little bigger.
The way the camera moves when entering a new room is kind of jarring.
Wait, I have a double jump? Nice.
