On Steam Deck I was able to minimize the TDP to 3W and the GPU clock to 200MHz with no adverse effects. No need to limit the frame rate.

Attempting to run the game under WINE presents mouse input and resolution issues.
Playing with a Steam Linux Runtime (i.e. native) works fine on Steam Deck's Desktop Mode (KDE X11), but not on Gaming Mode (GameScope Wayland).
As the game uses an embedded version of Chromium, it may be possible to set some flags which will allow Chromium to function under a Wayland environment.
PROTON_USE_WINED3D=1 PROTON_NO_D3D11=1 %command%
Native version was non-functional on my system, as it was rendering a blank window.
Forcing the use of Proton and setting the launch options to use OpenGL and disable DirectX11 has made the game render properly and it now seems to function without further issues.
This fix is also working for the other World of Darkness interactive fiction games made in the same engine.
