Bugs: touching the zipline at stage 7 of tutorial crashed a game with GML code error message I neglected to copy. The professor calls that you recieve with *T* is bizarrely mandatoty. I tried ignoring them but then they started on their own anyway at 50% opacity.
The first comparasion that comes to mind is Evoland, as a game imitating different eras of a genre. Platformer may actually be a better fit conceptually for that idea, because there are many distinct types of platformers throughout the years, but only a few Zelda-adjacent adventure games.
But that's assuming you actually explore different eras on a mechanical level, and not just with an aesthetic change. Because the 2 eras here play exactly the same, with only a handful of differing obstacles.
And the "do one level twice with disappearing blocks" gimmick feels terrible honestly. Realizing you can't actually make a certain jump and are forced to restart. Or just fumbling and touching more blocks than you need to. Maybe it's just a side-effect of the "empty space with clusters of platforms" design, you're often forced to make jumps up to the absolute limit.
I say choose different platformers you like, ape their styles and mechanics, and make them your eras.
