The game ran flawlessly on the Steam Deck, was able to clear the whole game with no issues.

While I did remap the controls to use the mouse functions via the trackpad this is not necessary if you don't want to, as the game does have controller support. Would recommend it though since mouse movement is much better.

One thing of note is that this game does not support Steam Cloud so all save data here is local and will not be backed up and synced across devices. It's not a huge deal due to the nature of the game, but it's something to keep in mind.
