The select menu looks nice.

Add a mouse hover effect and add arrow key controls (menu). Some control info text/boxes would be nice too (menu and ingame).

Bug: Game starts in select menu when pressing an arrow key without choosing a scheme.

haha, nice catch. So I will separate it after all.

For the control info text boxes I had another idea a week or so ago, but that’s not just for one game.

Should I open an Issue or do you want to fix it here?

1. Collect min one apple
2. Move right
