Yeah all the problems seem to be fixed now. Seeing the actual cutscene for the 3rd bug now, in the previous version the bloodthirsty slime was always spawned next to the left side wall of that area instead of the ledge it's supposed to jump down from. Since this is now fixed the cutscene will also proceed as intended.
Also, I think I reported this issue with fullscreen mode on a 1920x1200 monitor back in DD20, but it's worth mentioning again since it's pretty distracting. The black bars only work when the game starts in fullscreen, but it forgets about fullscreen setting on every run after the first one (starts in fullscreen for the unity splash, then always switches to windowed). Switching to fullscreen in-game causes this blinking garbage to appear, and going back to windowed mode doesn't restore the window size either: https://my.mixtape.moe/pkootw.webm
