simian.interface, by Vested Interest, is a game that never tells you the controls or how to play or what your goals are, but you'll immediately intuit all of those things just by interacting with it. In this sense, it's very toy-like: you're just playing with this thing, tossing it and turning it over in your hands. No instructions, hardly any rules.
Nominally, it's also a "puzzle game", but it really doesn't fit into the popular sense of a puzzle game. There's this concept of "filler puzzles" among puzzle games, where puzzles that don't demand any new skill or understanding from the player are not as valuable as more novel puzzles. You can be assured that in a Stephen Lavelle puzzle game, for example, every single puzzle has been consciously constructed and filtered and curated over the course of dozens of playtests. Same thing in Jelly No Puzzle: there's always a bit of additional new lateral thinking that trips you up.
In this sense, simian.interface is an awful puzzle game because it is made almost entirely of filler puzzles -- you're just doing the same thing over and over, and the shapes change a little bit. Most levels take about 15 seconds to complete.
... Except it's a puzzle game where the formal novelty of the puzzles doesn't matter?
