High Score Feature and UI tweaks

Hi,

Just added a high score feature, some balancing changes and UI tweaks to the game.

High Score will be recorded per level since the 8 (4 x 2) modes have different configurations.

Balancing changes should help to make the game more difficult, please let me know in case the balance feels off.

I would be happy to hear any suggestions, feedback or general thoughts. Please reach out to me on itch, disillusioneddev@gmail.com or u/DisillusionedDev on Reddit.
