Hey there, this is a really fun game, congrats!
I have some feedback if you're still working on it:
- It would be great if the player could upgrade the character to hold more items at once
- Another upgrade to allow the player to store some premade potions somewhere
- If the game used keyboard controls instead of the mouse you could easily make the game playable by two or more people
Let me know if you're still working on this :D
