Ok I beat the game. I was playing on a private Edge window because Godot games run better on Edge in my experience so I lost my progress when the game froze on me. It really made me wish there was a skip button in the story sections.
It does seem that there are quite a few bugs. Hp starts draining while the countdown before the match is still ongoing. The options menu does not open. Some of the cutscenes seem broken. 
When connecting two bubbles, the direction matters sometimes. A can connect to B while B can’t connect to A.
There are other things that aren’t bugs that are quite frustrating. Mint’s skill is very annoying because when a bubble gets too big it gets pushed outwards and can’t “hit” the wisps that fall inwards because they are small like sand. I understand that you don’t want to overwhelm the player with text, but I wish more of the mechanics were explained. How big does a bubble need to be to deal damage? How big does it need to pop by itself? How much skill charge do you get per size of the bubble popped? How big is the radius of a popping bubble’s area where it increases the size of the nearby bubbles or destroys wisps?
Still one of the best entries in the jam that I’ve played so far. This is some of the highest amount of content you can find in one entry in this jam and the gameplay is the most creative that I have seen so far among the entries I played.
