Ritual: Crown of Horns is a fun little twin-stick shooter. You play a gunslinger who was brought back from the dead by a witch. The witch needs to perform rituals in various places and the ritual takes 5 minutes to prepare. So your only task is to keep the enemies off the witch long enough for her to complete her ritual. Which means, yes, each level lasts 5 minutes. Perfect for the Steam Deck.
I know the game only has 35 reviews on Steam and even those are Mixed, but I really enjoyed it. It might be because the game regularly goes on sale for $2 (90% off). I definitely wouldn't pay $20 for this game, but $2? It's plenty of fun for $2.
Here's a trailer. You can get it on Steam, but like I said, wait for a sale.
