Images aren't loading in offline version chrome
And the index file isn't in resources foldwr
My knowledge of how the game runs on Mobile is very limited. So far the fix that @umbigo and others have found (loading the game from file explorer) seems to be the most viable solution.
As a fall back, there are some sites that host an up to date online version of the game (e.g Gamcore). And whilst playing the online version may not be as optimal as getting the offline version to work, the online version should load without issue.
Usually, if the files are in the right place and the usual methods haven't worked, it implies that there is something about the browser that's blocking the images from loading.
Try using the established file explorer method to load the game in another browser (Edge or Firefox work best behind chrome). If the problem disappears, then chrome is likely blocking the images. If the problem persists, then it indicates something might be going on with the game files.
In case we're unable to get the offline version working, https://gamcore.com/games/community_service is currently on Update v2.2.1. There's a lot of ads on the website (shouldn't affect the game window), but very few sites at the moment host an online version of the game. (Unfortunately I can't host on itch.io as the game exceeds upload limits. A dedicated online version is currently the next goal on Patreon)
