The pixel art is fantastic and gives the game a lot of charm from the very beginning. The gameplay is well designed for a game jam, although the time available to complete each round feels quite tight. I completely understand that, since we ran into the same challenge while developing our own game. With such a limited development time, balancing everything is never easy.
At first, it felt like you needed ninja reflexes to brew the potions in time, but after a few attempts I was able to complete both level 1 and level 2, so the learning curve ends up feeling rewarding.
I also really enjoyed the farming section. It almost feels like two different games combined into one, which adds a lot of variety and is especially impressive given the limited time available during the jam.
Great job!
