Mario Keys - a single player modification for Half-Life. Concept: Find color coded keys to open color coded doors. The game is set in a mario-styled world. Fun for all ages.
it's a me, mario on the keys
I LOVE IT
* basically an obstacle course mod, you never meet any real enemies.
* most maps are simplistic and the big ones have poor performance.
* a lot of guessing which key does what.
* you'll be constantly fighting a bowser cube which is pretty silly.
but it's ok
Good jumping/puzzle mod, but without usual enemies.
