We're not sure why the launching from the itch.io app doesn't work, but downloading the binary from the itch.io file website should work. There is also the option of Flatpak. We do not manage any AUR packages for Pixelorama, so we can't guarantee how up to date they are and how well they work. To compile it, you need to download Godot 3.5.2 manually (either from their website or Flatpak) and run Pixelorama as a project, which can be found on GitHub. We have plans to update to Godot 4 soon.
I appreciate y’all! I know it’s difficult to update to godot 4 if your project deploys to web. I understand about the AUR thing. I’ll message that package maintainer next. What I’ve gathered is Godot has changed the reference “godot” in linux pkgs to point to 4 latest instead of 3 latest so when u dl and install from AUR the pkg manager compiles with the wrong version. So, I’ll ping the maintainer next. Thanks for all your hard work. I can’t wait to try the new features!
