Okay, done with chapter 4 and NOW I'm sure I've done everything I can see.
Lanterngeists don't seem to be working at all. Takes damage from water+multi elem, and sometimes survives at 0 hp while softened?
Riftkeeper isn't gaining starforce from damage taken
If you spamclick Bad egg's intro, the music doesn't get a chance to load properly. Not very important though
Small Fortune doesn't seem to stack
That's it for the bugs, but I can't seem to find monster 208 or the ice jewel medal. Also, if you've got colorblind settings, you might want something similar for cliff climbing, I needed to go full screen to barely see that stuff. Also missing 1 sanctum key for the treasure rooms beside the end, not sure if that's intentional.
