Made this a long time ago, it's a WIP port/demake of the classic 1990 game Alpha Waves, or Continuum as it was known in some regions. Code is an absolute mess, this was the first time I coded a 3D engine from scratch and it really shows. Level data was imported from the original data files for the Atari ST version using a simple export script I made. I think this cart includes all the rooms of the starting area ('Dream'). My intention was to create a multi-cart release that includes a different cart for each area in the original game and use reload() to pull the level data and music from the corresponding data cart. If no other carts are present (BBS standalone version), a message would be displayed indicating the cart is running in single cart mode and no other areas can be visited.

Just a little demo I made a while back. Morph ball works, but not much else (there's a cool animated Ridley that hovers in place though). Sprites are 2-bit to (potentially) fit in more map data if I ever continue work on this and implement some sort of room compression scheme.
