Gateways initially seems like an 8-bit Portal platformer, but it grows to be so much more.
The story sorrounds a professor who has been trapped in his lab. He explores it, and in doing so recovers parts of his equipment, which lets him progress further. The initial gun fires simple point-to-point gateways, like Portal. But as more guns are unlocked, the game becomes more and more challenging and interesting, with Time travel gates, gravity reversal gates and so on.
The game doesn't take very long to complete, and I was able to solve the game first time without using any of the hints, but it still proves to be challenging enough in certain areas.
This game can be controlled by a controller, but I would reccomend against this, as using analog sticks it can be hard to accurately place the gates. Keyboard and mouse work much better.
The 8-bit graphics in this game are very nice. The map never looks particularly "static" in any way, with minor details
The music in this game is very nice. It's never too obtrusive and loud, and definitely adds to the atmosphere of the game.
There is a level editor (library>tools), and workshop integration so you can create and share your own maps. The level editor is easy to get a hang of, and the developers included an extra map which is available on the workshop.
I found no bugs while playing this game, and it never crashed on me. My only complaints are that the save points are a bit sparse, though. So if you die, you might have a long way to travel to get back.
Overall this is a great little platformer puzzle game, it's a bit short, but definitely worth playing.
