Sorry about the linux build! Didn't want to build for os's i cant test on
Arcade mode as the default was more for the jam than anything tbh, though in testing i did find myself preferring it? Maybe I'm just lazy lol
A proper tutorial and cleaning up the UI is on the to-do list! And yeah tuning down the parry difficulty is there too, though funnily enough the hurtbox size actually doubles when you're actively parrying lol
The first boss is 100% the "Parry or die" wall, so having trouble with it makes sense, I'm surprised you got past it without parrying to be honest!
Appreciate all the feedback, thank you for playing!
