Is there a way to transfer save data from 1.4 to the 2.0 prerelease? I clicked backup save data to Gamejolt, how do I access that and can I use that to move my data to 2.0?
I was wondering, what folder are the sprites in?
Okay I know I'm being dumb here but when logging into Gamejolt for the game, what do I do for the token thingy? (PS I'm new to using Gamejolt so I don't know the ins and outs for it lmao)
Is there any possibility that this game gets a steam release, possibly with steam workshop compatibility?
My game open and it says this and won't open (Check Article)
how does one mod the game?
do i gotta remake the entire game?
or is there something in the files that i didnt find when i opened it?

Is anyone having trouble importing audio files into the sandbox's radio? Dragging an mp3 file onto it (and even clicking off it) freezes the game until I close it.
