because i have the theory that you CAN make a mode on your Chromebook yes it might be hard but its bound to be possible. For an example i did add a mod to fnf (phoned version on itch.io) and added the skin and the song,i just dont know how to do the mapping
If you don't know how to actually make the mod proper, that has nothing to do with Chromebooks. Since the question was about Chromebooks, I assumed it was about running the tools in the first place.
Same, I've been designing sprites on my iPad along with working on creating a soundtrack on my Chromebook I'm just not to sure what to do after I have the required assets.
