Hi I get this error repeatedly and it just kicks me out of the game. Sorry for the inconvenience
Yeah, other players have had the same bug (check out the other comments). Unfortunately, it looks like itch.io has an issue with achievements, and I'm thinking about disabling them for now. The good news is that it seems to be device and/or browser-dependent; maybe you could try using a different device or browser?
I've read that the webmaster of CoGDemos is working on the bug on her end. Would you like me to update you when she fixes it?
I think you accidentally clicked on the blue 'Make your own games' link at the bottom, under the game box! ☺
(I didn't remove it because this should just be a temporary fix, sorry!)
By the way, I added an option to disable achievements in the game. If you'd like, you can try turning them off to see if that "fixes" the issues on itch.io. Sorry again for all the trouble–I have no idea why everything's acting up all at once this week, lol.
Hey there Legit, I finally managed to bypass the problem on COGDemos. You can now go back to play here. Sorry about the hassle!
