So far, I'm rather enjoying this game: it feels fun to play, and the controls, while a bit out of my usual experience, work well enough I think. ^_^
That said, on my machine at least, the game doesn't seem to save: using a save-point claims that a save has been made, but on restarting the game I only see apparently-unused save-slots. :/
I'm also seeing some minor graphical glitching near the bottom of the screen; nothing that seriously hinders play, but enough to be noticeable.
In case it helps, I'm using a dual-monitor setup, and my system specs are as follows:
OS: Ubuntu Linux 18.04.4
Laptop; Dell Inspiron 15 3000 Series
CPU: Core i7 2.4GHz (4-core)
Memory: 8GB
Graphics: GeForce 840M, 2GB (+Intel integrated
