Hi,
Sorry I don't have much to go on at all, but would really like some help finding this game:
It's from around 1994-1997, and could be on SNES/N64/Megadrive/PS1 (or a system from that 93-7 era).
If I remember correctly there was a short right to left (maybe 2.5 or 3D?) section at the beginning, either underground or in a cave system before the game turned into a more regular platformer/side scroller.
If I recall most of it was set underground, and it was similar to Flashback/Out of this World in terms of cinematic elements but a little more arcadey (so like a mix of those and Prince of Persia/Castlevania/Abe/EW Jim [that type of platformer, but with a little more of a SF/apocalyptic feel to it]).
Again, sorry I don't have more to go on. It's a platformer I used to speed run in an hour or so, and was very good for speedrunning iirc. If I remember any more specifics I'll add in. Any help clawing this one back from the brink would be very much appreciated.
