Absolutely incredible!!!!! Very well polished, every boss fight was a struggle, and each boss had quite the dramatic entrance! The potion mechanic really felt like experiencing the side effects of your combinations, especially after I noticed the bubble ingredient affected the enemy's bubbles too.
I never figured out how to get the pig plushy though.
I think it might be cool if your bubbles could pick up items for you, sometimes when I defeated an enemy on the ceiling a heart would spawn but I couldn't jump high enough to reach it. There was also one spot to the left of the starting bed that if the red blocks were active and I tried to jump up the platforms, I would get crushed between the platform and the red blocks and die.
Great story, art, and music, and fantastic job with the game mechanics too! Bravo!!!
