Hello, and thank you so much for supporting Linux! I just completed Version2 and enjoyed the early gameplay. Performance wise, It ran very well!
Here are the components/OS I tested It on:
OS: Linux Mint 19.3
CPU: i7-3770k
GPU: GTX 1070
RAM: 16GBS
(I got about 150-200 FPS on the 'Epic' settings at 1080p)
Since this is only in early development, I didn't expect much from it. So far, I personally think It's a nice beginning.
Again, thanks for having a Linux version! I hope to see more from your project soon :)
