Game doesn't seem to work in Firefox (114.0.1, Win 10).
The game loads to the title screen with the level numbers at the bottom, but they're all grey. Tried in Chrome and it works as intended.
Finally figured out how to start the game but then realised there was something wrong with my shot's power (seems way too weak, looks nothing like the demo gifs).
So I tried opening the game in Chrome (I usually use Firefox) to see if the physics were different but now the overworld controls (cursor keys) don't even work.
Experienced a visual bug.
Got a Treasure Dummy after a boss fight but one of my dudes was dead so I restarted the mission. Then for the next fight I was fighting two enemies but the Dummy's card stayed in the middle until the fight was over (I didn't have to fight the dummy, it was inactive so it's escape timer was static)
