First of all, make sure that you use a supported browser. Support is limited to up to date Chromium based browsers, which includes the latest version of

• Google Chrome
• Microsoft Edge
• Brave
• Opera
• Safari
• Firefox

The game also works on Android and iOS, but on iOS the touch input is broken so you need to connect a mouse/touchpad/keyboard for now.

If you still can’t get it to work, leave a message here describing your issue. Make sure to mention what browser version you use.
