One recurring theme Jeremy Parish talks about in his Game Boy Works series are developers attempting console perfect graphics without adjusting for the resolution of the handheld, and this series is probably the definitive example of that folly. The graphics indeed look as much like DKC as they possibly can at the cost of some very cramped level design. The platforming also feels much more jittery, and the game gets very weird about pits during vertical sections. I ended up stopping at a level requiring jumping on lifts to change their direction, with it being impossible to tell which direction the lifts would go when playing on actual hardware.

That being said, the GB take on Temple Tempest is a bop.

Since this page is missing a lot of context, this game was developed by Phr00t, who specializes in procedural generation (and VR now apparently). The game was released on Desura (RIP) back around 2012, but thankfully is now available for free on the dev's old website for the game: https://gentrieve.wordpress.com/

This game falls into a lot of the same proc-gen pitfalls - room design is a planner's nightmare but also fairly samey once you've gotten past a couple "worlds", and enemies are either spheres or squares with spikes and turrets grafted onto them. Still, the design is never incoherent and worlds are short enough that the game keeps moving, and I think the textures and music help give the world a hostile feeling to it that keeps it from feeling like generic assets thrown around. I've never stuck with it long enough to finish it (assuming that's even possible), but it was nice to check back in after 10 years.

A big step up from Toree 3D, thanks especially to improved level design. In hindsight, Toree 3D suffers a lot from platforming cycles where you either get the timing exactly right or have to wait for a car or platform to get in position. Here, the design is all based on maintaining momentum, which works a lot better for the speedrun platforming style it's going for. (It also helps that a third of the levels don't have ice physics.)

It still could use a fixed camera in some parts, though, and the final boss is pretty weak. Everything else is a bump up from the first game, though, and the soundtrack is really stellar.
