I wonder what kind of animal he is.
Some kind of bird maybe?
I really like the pixel art and the game concept but I was compleatly lost at first because I tried to put the bucket of water into the measuring cup and not the other way around.
A tutorial might be nesesary for the first potion or at least a in-game help page to explaine the basics.
This is a bit of a nitpick but I found the voice-sound effect a bit to monotone.
But once I understood how the controls worked I started to enjoy the game. It remindes me a bit of VA-11 HALL-A which will always be a complimet and I hope to see more from this demo/prototyp.
Also, I like that the liquide moves when you move the full cup, it's a really nice detail.
