New update for this, just wanted to make some adjustments so this game could work better on Android, then put it for Android. You can now download the APK. No idea if I will ever put it in F-Droid or the Play Store, but it is available if you really want it.

Without further ado...

GUI Adjustments

I've made some GUI elements bigger, as well as making some elements that were previously images Godot UI Elements. This makes the interface friendlier for mobile, as well as making adjustments to text easier. Also, some items that used the default Godot UI theme now have a custom look.

Every GUI Change:

• Title screen buttons and "Begin" button now function identically, now scale dynamically, and are no longer texture-based.
• The settings, credits and back buttons are now slightly larger and farther from the corners.
• The "Mute Sounds" toggle no longer uses the default slider theme.
• List Settings (Colorscheme, CPU Difficulty, Speedrun Category) now have larger buttons and labels.
• Added a background to the Record Time display.
• Adjusted the look of the "Restart Game" and "Back to the Main Menu" buttons.

Colorscheme Display

You can now view the currently chosen color scheme directly in the settings.
