Heads up: On Linux, the game fails to launch if the sandbox is enabled in the itch app settings.
In case this is an issue on the game’s end, here’s the relevant snippet of the event log:
Exit code 0x1 (1) for (PaperLilyDemo.x86_64)
Had error:
→ Standard error ================
Error mkdir: util.c:836 create_empty_dir_as_root: Permission denied
====================================
→ Standard output: empty
Relaying launch failure
Edit
Also, trying to load the save state from the end of Project Kat, the one with Lacie that mentions chapter one, seems to just soft-lock the game; the loading screen never goes away, even with no disk activity in sight. I’ll probably send an email later if this comment isn’t noticed in the next couple of days or so.
