Playing on my PinePhone Pro on ArchLinux using Backbone One controller. Some missions are super hard because the game does not have any aim heper for gamepads. The game runs mostly smooth, but sometimes I experience small yet noticeable FPS drops depending on the weather and time of day.
I also have the original PinePhone and bought Pro because the original is to slow :) Pro is way faster then the original, but is still slow compared to modern phones.
Yes, the controller is pricy. I tried buying GameSir X2 Pro first. It works with the original PP, but can't charge and play with the Pro. I talked to megi about it and he said that the issue in the gamepad. Also it doesn't have a headphone jack. So I sold it and bought a Backbone.
