Below is a summary of known problems and their solutions. First, make sure your computer meets the requirements stated on the game page.

The game is not fullscreen or the scaling is wrong

Kubitron is intended to run in fullscreen mode. If it is not, or the scaling is wrong, so that all of it does
not fit to your screen, having a font scale in windows other than 100% might affect this. Right-click
your desktop, choose “monitor settings” and under “scale and layout”, and make sure size for text and
applications are set to 100%.

No sound

The first time you start Kubitron, your anti-virus program may interfere. This may cause the sound to stop working (and not just Kubitron, but any sound source), and the only solution I've found is to restart the computer. Sometimes it comes back after a while anyway. I have no idea why this happens, so please let me know if you know how to prevent this.
