Works great, even with all the explosions and enemies the game runs solid
gamemoderun PROTON_DXVK_ASYNC=1 %command%

Tested with Proton experimental and Proton 7.0-6 and works on both, it launched somewhat faster on Proton 7.0-6 for me but performs the same.
Playable but can be choppy
Game will have random performance hiccups on standard Proton, Experimental, or GE. Not sure if this is in Windows as well as I have not tested there.
If you have performance issues, try with or without vsync and Proton GE and see if that helps

It's a hoot to play, and stays above 100 fps with Glorius eggroll Proton build 7-20. It's good with regular proton, but not as amazing as with the GE one.

Works great
Was unplayable with controller (Xbox Series) for me, acceleration was too much. (Your experiance may vary) Tried changing some settings but didn't find any acceptable solution.
Changing setting with controller was a issue, especially sliders.
Apart from the controller acceleration issue, runs great. Got > 120FPS on my system.

It works but performance fix would be nice to have
Minor stuttering. Despite FPS is always 60, sometimes it feels like it's a bit lower

gamemoderun PROTON_DXVK_ASYNC=1 %command%
When unlocking boots everything is black
High settings barely 40 fps had to turn it down to low without any effects to get around 80 fps

gamemoderun PROTON_DXVK_ASYNC=1 %command%
Some stuttering and lower than expected performance, given my hardware.
Played the first few levels of the demo. Works really well other than some general stuttering and lower than expected framerates.
