Blade of Agony runs really well on my Windows 7 install on my skylake rigg.
I installed to my Arch/sklake set up with the flatpak version. The install went easily and the game ran. However for some reason the graphics were very blocky and the game did not run as smoothly as the windows install. This is a shame as installing was a easy one click affair just as advertised by the flatpak folk.
I have not tried out the snap version yet.
Nearly forgot, if you try and get stuck throwing grenades in the training session the answer can be found here,

you will need the information if you want to throw grenades or kick someone anywhere in the game.
