Those who played our game found our level design very good... Our take on the theme was "Only one platform", but you can move it throughout the level. But there's things only the player or the platform can do! The player is able to go through a force field that the platform cannot, and they can go inside a portal as well; and the platform can deactivate lasers, recharge the player's jetpack, fit through tight gaps...

The game I liked playing the most was Blastsmith, it's about a blacksmith who can only carry one item at a time, which often means you have to think very carefully about which items you pick up, because you could have to throw them out so that you can pick another one, and waste a lot of time. I got almost 500 coins, let's see how many you can get ;)
