To play Maze Maniac on your computer, you need an emulator (find out what is an emulator with google). Maze Maniac was built with the Virtual Colecovision emulator. Download the latest version (for Windows95 and +) directly from their website.

Then you need the rom of Maze Maniac.

Now unzip both the emulator and the rom in the same directory. Just drag the rom file over the emulator. You are ready to play ! Enjoy !

You can also download the manual.

Please note that it might work with other colecovision emulators but I haven't tested any. If you happen to play it with an other emulator, please tell me.
