Sorry everyone but save files don't transfer to this new update. To transfer save files to the new update:
Windows + r -> search $appdata$ -> search for "okin" -> go to "Okin-1750661007" -> copy all save files -> go to your 0.3 folder -> game -> saves -> paste them there.
I only know how to do this on windows but hopefully it's similar on mac/linux. Really sorry but will hopefully be worth it for smaller download sizes moving forward
