Game play works well, but runs slow.
I would say the game on this Arch just works, but too slow to be in a playable state. I upload this patch mainly for 0ad lovers using riscv or people who are interested in riscv to try out. It is totally fine for me if this patch is left unmerged or ignored.
This arch probably will need more time to evolve, but it is very promising and fast growing with all major distros supporting it already.
