I, like a few others here, participated in the Ludum Dare game jam and made a game in 2 days with Unreal Engine.
2 days ain’t much to make something playworthy, but I gave it my best. The outcome is a lunar lander type of game. You have to fly around and first and foremost try not to crash horribly. If you managed that, you can pick up building materials with your beam and transport it to the bridge to construct it. I made it pretty **** hard to finish a level, because I like hard games that give you a bit of satisfaction beating them.

I recorded everything and I had roughly 30 hours of footage so I made a timelapse video of it.
