Windowkill is a twin-stick shooter where the game window itself is constantly closing in on you. A really clever idea, and a game I had a lot of fun with previously and now it has improved Steam Deck support too.

Windowkill is a fantastic twin-stick shooter, where the game window is constantly shrinking on you and enemies spawn across multiple windows. It's truly clever and now it has full customization available via the newly introduced modding support.

This might be one of the most unique games I've ever played. Windowkill from torcado just released on Steam with Native Linux support and its use of multiple moving windows really changes the bullet-hell genre.
