Tell us what to fix
The game now says plainly that it is in alpha, and there is a way to write to the person building it — from the help menu, the drawer, or by email.
The game is in alpha, and now it says so. A small marker sits beside the logo on every screen, on the sign-in and sign-up pages, and on the public pages. Things may change or break; that is what an alpha is for.
Which makes what you notice the most useful thing in the game right now. Open the help menu in the header — or the drawer on a phone — and pick Send feedback. Say what went wrong, or what would make the game better. It goes straight to the person building it.
If you would rather write properly, the same panel gives you the address: cyril@sgame.to. Either way it reaches the same place.
