Starts well
Played with Proton 9.0-4.

The game works fine but it has slowness on some levels
On later levels the game can slowdown when multiple robots are destroyed.
Saddly the game depends too much on the framerate, you can lock the framerate to 60 but it will slow from time to time.
Varying slowdown... Some parts you're in slow motion from lag and some parts it runs super fast.
Only play if you have a fast machine
Not sure why it's marked as unsupported.
On Steam Deck, aftet the tutorial, when selecting the first level an error screen pops up multiple times. Simpley hit ignore until the error screen stops popping up. The game plays fine after that.
Works fine out of the box on steam deck as far as I can tell. Not sure why it's listed as unplayable on steam deck.
Works out of box
Played with Proton 6.3-8

Working Perfectly OOTB
(Not Proton Problem) Stretches window on non-16:9 resolutions, rather than using black bars.

All the issues I encountered can happen on Windows as well, Proton handles this game perfectly.
The game ran butter smooth, no slow downs as other people reported in my case.
The game is locked at 60 FPS and screen resolution to maximum 1080p, but not because of proton. Everything looked perfect on my 1440p 144hz screen.
Found no issues testing with xbox one controller
Works Fine - Funciona Perfecto: https://youtu.be/uIS_Z9d9J2s
The number of levels where you can feel the slowdowns are few and skippable at worst
The game slow down more than it should when a lot of ennemies are killed

With a PC Gamer maybe, u could have a nice experience
Sometimes it's freeze when the enemy blows up
Slow down is too much for a fast paced game such as this.
Absurd slowdown on Airship and when Particle effects are displayed (can be disabled).
Very Slow on Solus
Significant stuttering and lag that I don't have in any other 2D game
just needed to set "PROTON_USE_WINED3D=1 %command%" in the launch options and it worked fine
Works like a native
No issues
Runs fine
Shows some lag from time to time.

Played with Proton 5.0-7 and command params PROTON_USE_WINED3D=1 %command%

Works perfectly with full controller support

Worked perfectly with controller with no tweaks.

Everything works fine including gamepad support, you don't have to do anything other than press play.
