I gotta say, I love the new update, but I did run into a problem with it I never dealt with before on older versions. As the game progresses, the game becomes slower and slower with certain actions. Like, when you press continue, or try to attack, it can take several seconds before the action is carried out. This especially makes the last 2 bosses a bit of a chore to deal with, as they're already long enough fights as is without this weird problem.
And I'll say now, I did 2 separate playthroughs with both the warrior and mage on google chrome, in incognito, playing both on itch and on the downloaded html, which has not given me any issues before. If you need anymore details, feel free to ask.
