The game felt like it had significant input lag, and at 720p with upscaling text becomes very hard to read. The game's visual style of "glitch" effects also translates badly with upscaling and I really had a tough time actually understanding what I'm looking at on the screen.
Perhaps the situation is better on OLED.
It's the #10 top most played game on Steam Deck.
The game on new machines is quite impressive, quite unlike anything else made.
