I looked around on their old facebook page and apparently, it got rebranded as Roboland : The lost oasis - though it seems like that project has been postponed too. Something is telling me that their team is simultaneously working on both the new and old game at once. Also, after looking through firefox's devtools and checking this game's certificate, it's going to be valid only until 21st of April this year, so chances of seeing the developers being active on kongregate for maintenance are pretty high.
All we can really do is wait...
Just like others said before, the game really isn't loading at all anymore. Had an error earlier today which said "ruffle failed to load the required ".wasm" file component"
Maybe it's under maintenance for the voting event countdown to be fixed (hopefully)
