Whenever i try to log in, I'm able to interact with the game for about 5 seconds before a maintenance mode warning pops up and I'm automatically logged out. This has been happening for at least 3 hours and i noticed there were people online and posts being made here

i have the dame. It has been like this for a bout 15 hrs or so. The pallia pearly were released before the maintenence od doom. I technically played a little.when the reload button at the bottom appeares, you land on your last page. Its enough to gamble and get the furrymon money

Yes, the game has been under maintenance since yesterday.
The right thing to do is to develop it on a separate branch and test it locally, so they only need to take the site down for a few minutes to upload the changes, but this and a few other things made me realize that the devs of this game are inexperienced, so we need to be patient.
(I'm not speaking ill of the devs, everyone has to start somewhere. The artist has already admitted that he pays devs from third-world countries for development, and as a dev in a third-world country myself, I understand how beneficial this is for both sides.)

If I have to guess, the dev might just have forgotten to turn it off, as far as I can see, nothing seems to have changed in the game in the last like 10 hours.
