Downloaded the game in itch, and all three launch options give errors. Play in browser works, on both my linux machine and on iOS. Attempted to attach screen shots of error codes.
This seems like a specific fontconfig error - I found something that might be this, but I'll need to check again first - https://old.reddit.com/r/RPGMaker/comments/digb14/rpg_maker_mv_162_linux_bug_arc... Were the previous builds of this game working for you? Did you upgrade your Linux to a higher version recently? I've been using a 1.6.2 version of this game system this whole time, so I need to check if it might be a compatibility issue
I am running whatever is LTS as far as the kernel and base progs, and on the itch.io launcher it is currently 25.4.1, butler is 15.20.0, and the itch setup is 1.26.0. I hadn’t tried a version of your game prior on my Linux box because it was working on Firefox for my iPhone. I do however have the V0.0.9 of your game, if I can load it into the launcher and see if it works? If not that site you referenced does suggest a fix, which I may try as well.
I will try those tomorrow and see how it goes. I’m really looking forward to seeing the extent of the game, since I love RPGs in general. If mobile browsers didn’t like to fail on me after a couple hours of gameplay I’d have likely not run into this issue. Resetting my progress after 2 hours of grinding/gameplay is never on the top of the list.
