Very cute. I like the mechanics of the potions and the mushrooms. I didn't get past the first level though. Something about the physics feels off. And the level was too hard while still getting used to the controls. Would be nice to include W as an option for jump, and the arrow keys as an alternate (for those of us with tendinitis.) Also, some of your Settings controls are conflicting with browser controls - ESC closes fullscreen, Ctrl + W closes browser tab.
