the reason the original game was put into limbo, the main mapper moved to japan, so the project has been on hiatus, but ive started on remaking the N64 game, although it wont be pure CV64, we're adding to it, updating the mechanics, and trying to bring it to the new generation of players while still keeping true so the older players who played the original will still be like "I remember this"
First release is on a modified IDtech3 engine, im looking into doing a UTengine version and possibly a source version, on a side note for resurrection, I have some dreamcast dev tools I could make an ISO version of the game for Dremacast players.
the team is also looking into making our own 2.5D engine modifications, eg Mirror of Fate, DXC, for games as well
