Hullo, As you might have heard, the Steam Deck launched last week. We believe Project Heartbeat is an excellent game to play on the deck. Unofortunately we haven't been among the lucky few who received a devkit from Valve before release, so the game is not Steam Deck verified. We will verify the game as soon as we get the ability to do so. In the meantime, it's likely PH already works on your Steam Deck if you have one, Liam from GamingOnLinux tested the game and said it worked fine, so while we don't have an official blessing for Steam Deck verification we reckon the game should work fine already. Obviously Liam didn't conduct an exhaustive test, but we don't think there's any reason why PH shouldn't work on the Deck. A few versions ago we did a lot of work to support all different aspect ratios (this includes 16:10 as in the Deck), as well as improvements surrounding controller usage, mouse hiding and other funky important things. This very post is visible on a Steam Deck by pressing the compatibility details button on PH's library page and pressing Y.

We have reserved a Steam Deck as normal costumers for testing, we are scheduled to get it before the end of March, hopefully sooner than later. Happy button mashing. -EIREXE
