Also bought a copy of Jumping Flash recently, which I've been breezing through. I've played that opening level multiple times over the years given its knack for appearing in Japanese demo discs, back when I was dumping and documenting those as a hobby. But as someone who didn't grow up with a PS1, I never otherwise played it in its time, which I decided to finally amend since it's so cheap and ubiquitous here in Japan. I've always been really fond of the visual style; there's not necessarily a lot of coherence to the levels and what populates them, but they have a pallette and general style I'd call SIGGRAPH-adjacent. Between the bright colors, abstract imagery, and constant checkerboards, it's pretty clear that one of Exact's mission statements with this game was to make a game that feels like you're playing inside a Silicon Graphics workstation tech demo or something, the kind of thing you as a random member of the public only saw in magazine shots or maybe in, say, an incredibly grainy QuickTime video. It's easy to see how it impressed in the sort of environment it came out in. Somehow it still works, though, and the impressively thoughtful platforming controls for what's pretty much the very genesis of such games in 3D makes it a charming pleasure to play. There are plenty of reasons why it got quickly outclassed by subsequent competition, but it's a fine representation of both the PS1 in its earliest days and also the kind of developers Sony recruited to give the system traction in drawing from the X68k scene.
All told, a relaxing game after a long and pretty hectic work month. I dig it. đ
