Using the Steamdeck's built in controls: Standard attacks, performed by tapping the right trigger, can sometimes "stick" when attacking repeatedly and instead charge into a power attack that won't fire untill the trigger is pressed again. This can be a bit irritating during hectic fights, but is hardly gamebreaking.

FMV files, which the game uses for multiple secrets that I won't spoil here will not play correctly when playing on Steamdeck. While the audio, which consists only of atmospheric music, DOES play, the actually important video does NOT play forcing the player to look up the footage on youtube, significantly breaking the wonderful sense of immersion the game creates. A second, much more minor, issue is that the menu of the leaderboard at the end of one of the game's optional challenges can't be navigated or closed with gamepad controls and must instead be operated with mouse controls.
