Hi! Thanks for reviewing it! The random movement with WASD is intended and not a bug. The idea was to make the survivors "randomly" move through the sea by praying (hitting WASD, hence the game's name).
The Leaderboards work when you play offline. I think the the webplayer can't communicate with outside servers when hosted on Itch.io. Consider this and the bad performance when on the WebGL version.. I probably should make it only offline....
Anyway, thanks again!
