The Steam Deck’s multitouch screen might be its most underutilised feature. Until recently, I wasn’t even sure whether devs could use it for anything more than simple mouse emulation. But I’ve just started playing “Sky: Children of the Light” on my Deck (which is generally a great experience on Deck, especially on the OLED with 90Hz HDR) and I found that when using a musical instrument, you can actually use the touchscreen to play up to 10 notes at the same time.
This got me curious: Do you know if there are any other games on Deck using multitouch, or is Sky the first one that does it?
Most PC games probably won’t support multitouch, I’d guess you’re most likely to find it in games that have a phone version (or started as a phone game).
I don’t know of a good way to identify those games though. My best guess is to look at some of the curated lists of touchscreen friendly games (example 1, example 2) and look for games that are available as a mobile title and would benefit from multitouch support.
