Gateways, an exploration-based platform game from Smudget Cat Games, can be quickly summarized by saying it's like Portal, but in 2D. That's leaving a lot out of the equation, though, as Gateways goes to great lengths to provide a different kind of experience, one more akin to a metroidvania-type game than that other portal-making adventure. You'll realize that as soon as you start to explore the chunky pixel laboratory, smashing the glass domes over monkey's heads and wondering how on Earth you're supposed to climb over the next ledge.
