Tower Of The Wizard

Tower of The Wizard: Gameboy Adventure (full title), is a metroidvania platformer at heart.

You need to explore a vast, open castle, and use your map and your skills to progress.
The game is a love letter to the old platformers, and is very challenging.
You will need a lot of patience and practice to progress in the game, but once you finally cross a pesky section by pulling off a series of connected maneuvers, you will feel like the biggest badass of them all!
