We've received a lot of feedback about the main menu buttons being hidden (making it impossible to even start the game) or being cut by the screen border. This happens for Windows users if the setting Change the size of fonts, apps, and other items (in Settings -> Display) is set to more than 100%.

For now the only solution we can offer is to change the setting back to 100% when running the game. We realize that it is very inconvenient and we apologize for that. The problem seems to be with the game engine we've used. However, a bug report has already been filed and we're waiting for a solution. Godot's team is very responsive and helpful and we hope they will either fix this soon or suggest a workaround.
