Played through 64 a few years ago, still holds up great.

I should really play Legends 2.

Try the Steam Link app from your phone. I haven’t tried it with Balatro but I think it worked fine with Slay the Spire.

Try turning off Bluetooth. Try turning off ipv6 in desktop mode. Could also be interference from electronics near your router or Deck, like a computer or your neighbour’s wifi.

90 degree angled USB cables are a godsend for this.

The characters are all very different but the environments look extremely close. 0:18 in the trailer is Greenpath.
