Wow! Only watched videos of the original a while back, was surprised to stumble upon this, it seems to recreate the game spectacularly well! The animations and the music are very pleasant, just like the original game, while the level design feels like a well thought out port for the Pico-8's display.

Yes maze layouts had to be different, Intellivision had a wider but shorter rectangular screen, 20x12 blocks, while Pico-8 has 16x16. By the way to make a few layouts looking more familiar I recreated similar regions and corners, or -especially forests- making them narrower and adding more at the bottom.
Thanks for playing it!
