Pretty satisfying feeling to increase the level of the potion you can make. I did it to the last possible potion, but it feels like at least one more mechanic, like mixing the potions, would increase playability a lot. Good job overall!
Good job on making it to the last one. I agree the game is pretty (really) empty right now, in terms of content. I'd say it's almost out of theme because of that... but I'm gonna work on it after the jam, since I've had a blast making it! :D
