The phone is an oneplus6 with postmarketOS. VoxeLibre runs on minetest 5.9.0 dev, compiled from source. I played for about 30 minutes and it cost about 20% battery. It runs butter smooth and has no input lag at all. Must be one of the best mobile gaming experiences I ever had. A little optimization would be great down the line but i was surprised how good this is!
Is it playable with touch controls?
Yes! It works great!
