Thanks for giving it a spin! It was a blast revisiting the old Game Maker 6 engine for this project. A bit of a nostalgia rush on two counts.
As for my managing to slim it down into 4MB, it wouldn't be the spiritual successor to "Wizard" without a smaller file size--I hear the original Wizard prototype was the last of the 2KB Atari games. Chris Crawford fit in so much awesome into a 2600 cartridge. Shame it didn't see the light of day for many years after the decommission of the Atari 2600.
