Läuft prima auf dem Deck. Jedoch sollte man wie beschrieben das Controller Layout passend aus der Community laden und nutzen.
1 FPS. No tweak helped.
The game seems to work, but at 1 FPS. I tried various proton versions and flags, but nothing helped.
Finished game without issues
The stuttering is bearable and otherwise Aggelos can be played well
I had to assign the keyboard keys to the controller via the Steam overlay to be able to my Controller.
Stuttering especially in water temple.

Frame rate stuck at 57/58 FPS
I didn't have any problems

Used keyboard only to test, hardware is pretty old so i assume this was the reason there was a bit of framesskips. Didn't notice much difference except the frameskipping when comparing with my windows computer. Other than that, i could play and enjoy the game.
Added launch options:
PROTON_USE_WINED3D=1 %command%

Only the upper left corner of the screen is displayed for me. Technically I could start playing, but couldn't see anything.
I could force the screen to render entirely, albeit in small window, by minimizing the window and restoring it, but moving to a different menu required me to do this again. Sadly, while I were able to go to the options menu this way, I couldn't find a way to enable a normal windowed mode, so the game remained unplayable.
