Will versions v0.14.1 and v0.15 be released in a single update, or will they be separate? Also, how much time is left until the update is released?
Separate. So v0.14.1 will be released here for free when I finish v0.15 on my patreon. v0.15 will come here when I finish v0.16 etc.
As for a release, it'll be a bit of time for the next release on itch, since I'm skipping releasing v0.14 here. But v0.14.1 is coming along really well and I'm close to having an offical release date for that update
