Free horror platformer that starts as a cute Mario-like; the HD version came to Steam later.
The Princess of the Flower Kingdom has vanished! She was taken by the Ghulibas of the north, and it is up to brave Zee Tee to rescue her. On his quest, he - and you - will discover the hidden lands behind the peaceful kingdom, and come face to face with secrets that will set you on edge!
In the spirit of Super Mario (1985).
