Has anyone played (or heard of) Jumping Flash! (or its sequel) for the original PlayStation? I really like both games a lot, and it's really cool historically to look back on a game that really blatantly feels like a very early 3D platformer, but still gets enough right to be really fun all this time later. They're silly and lighthearted and you play as a robot bunny!! And there's a really big emphasis on jumping really high up and I love that.
I think another reason the games are historically interesting is that I think it's pretty likely that the Bubsy 3D developers took inspiration from Jumping Flash! because they have a few strong similarities in how they control and work, and there just wouldn't have been many other 3D platformers to look at for inspiration back then. For instance they both have tank controls and do the thing where the camera can aim down at the ground during jumps, which works a whole lot better in Jumping Flash! than in Bubsy 3D.
