I'm having trouble starting the game on Linux; it just hangs with a black screen until it's force quit. Same issue with the demo (I should have checked before I bought it but I haven't had problems running Ren'Py games before...) Tried the Windows version on my Win7 laptop and it seems to be running with no problems. Not sure what the issue is.
Here's my system specs in case it's helpful:
OS: Ubuntu 18.04.6
LTS KERNEL: 5.4.0-92-generic
CPU: AMD Ryzen 7 1700 Eight-Core
GPU: NVIDIA GeForce RTX 2070
GPU DRIVER: NVIDIA 460.91.03
RAM: 16 GB
I can also mess around in the script files and test some things out if you let me know what to look for.
