So, regarding the starting problem, I just tried the latest patreon version and the latest public version from majalis site (0.2.24), and I have the same problem with both. Neither the exe nor the jar file work, I only get the loading symbol for like a second, but nothing happens. Since the problem exists with both versions, but I was able to play older versions of the game (don't know which one I played last), I'm still not sure if the problem lies in the game or my system. Java is up to date and I installed the right version for my system. There's also no problem with my anti virus software. I also tried running the game as administrator, but that didn't help either. And if all of that wasn't enough, my tablet won't install the andoid version.
Are there any configuration options inside Java that might have changed or need to be changed?
Update: I just tried running the pure Java version instead of the windows executable version, and it worked! So I guess there's a problem with the windows version.
