Changed it to get the asset prefix entirely from the backend.

[chownces]

lgtm. might wanna add assetsPrefix to src/pages/__tests__/localStorage.test.ts to standardise it (even though its undefined)

not tested yet as assets are not renamed atm

[gok99]

tested with updated backend, and all seems to work!

changed the game module remote path to a function, will update the modules side accordingly
