Super Sonday is a fun 2D action platformer for Windows, developed by Sergio Stuff. The game follows the story of Sonday, a young girl who can transform into a powerful tanooki to save the world. The objective of the game is to collect the stolen pieces of Sonday's family heirloom, the Sonday Stone, and prevent it from being used for evil purposes.

The game features 8-bit style graphics and gameplay, where you'll collect weapons, health, and power-ups to defeat your enemies. The levels get progressively harder as you advance, making the game more challenging. You can control Sonday using either a keyboard or gamepad controller. The game also includes a password save system, just like 8-bit systems of old, so you can start where you left off or replay your favorite levels!
