What is the best way to play id Software Doom (1993) on a KaiOS device? Googling "doom kaios" didn't return any results. I wonder if it is available from the KaiOS store in one form or another. I wasn't able to search the store since I do not have a compatible device.
You will need to provide your own DOOM2.WAD, then import it into the app (open KaiOS file manager, click Options -> Share -> Freedoom). You can copy DOOM2.WAD from your old Doom 2 CD, or buy Doom 2 on gog.com .
There's no netplay, because netplay is complicated for various reasons, but it might be added in the future.
And there's no music, because OPL3 emulation is very CPU intensive and slows the game to a halt.
