So the initial playthrough, there were a lot of problems, some old, some new:
Old problems:
1. The candy factory solo run still has invisible party members pushing Mari from the tube (Already made the same comment on the WGaming fourm.
New problems:
1. Game crashes when trying to interact with the dev girl to get to the new content (See 3rd pic)
2. Weird boundries for the signs with the water strenghs and weaknesses (See 1st pic)
3. The game seems to be soft locked on the water statue fight (See 2nd pic, and yes I did wait a while to see if it would do anything, but didn't do anything after selecting an attack, a little bit more playthrough and it seems like it's only this attack that has a problem)
4. The stone snake seems to allow for infinite blades apparently
5. The water rune doesn't seem to work at all when you step on it even when water bloated for the door that leads to the statue
Also, a lot places that should be out of bounds can be accessed through bounce
Probably will find more bugs and issues with some more testing, but these were the main ones I found with a quick playthrough.
