"Gateways, by Smudged Cat Games, is a puzzle/platformer that borrows heavily from the Valve series, Portal. You play as a scientist trapped in his own laboratory with no memory of how you ended up in such a situation. Starting with nothing, it’s your job, while making your escape, to gather your equipment and piece together what happened to you. If you’re going to rehash a well-established mechanic from a beloved game series with a more than devoted fan base, you better do it well. Gateways does it…decently."
