And it's important to me that once you understand the idea behind a puzzle, you can immediately solve it instead of having to go through a cumbersome, frustrating execution.The story is minimal, just enough to give you an overarching goal to pursue, and then sets you free. You'll no be given generic Metroidvania skills that have just one usage - if you combine your abilities, the possibilities become even bigger. Puzzle types that I already knew from other games were immediately rejected in the design process.
