In the first gif the most noticeable thing after he changes frame is when walking left his sprite is getting replaced with a wall tile? The boss is flashing, and a bunch of background tiles have just gone missing it seems.
In the second gif the most noticeable thing is the giant flashing backdrop image suddenly appearing in several places, like when I wall-kick. Let's not forget the guy stuck in the ground and in perpetual pain no less.
So, part of me is kind of nostalgia-proud, but, the other part of me is terrified. I've never seen anything like this and it has just happened after I did a full system reset and clean installs. Someone suggested it might be the steamworks API. I guess I will build an older version without steamworks and pray. Does anyone have any other suggestions ?
I just built an old version without steamworks and no glitch
Steamworks + new fusion build = glitches
