Dear Quantum Sleeper Community,
From the dark corridors of horror to the warmly lit streets of tomorrow - we're taking quite a turn with our next game: Sweep City!
After keeping you on the edge of your seat with Quantum Sleeper's LIDAR, we decided to try something completely different. Trade in your fear for a street sweeper, and instead of running from darkness, help us clean up the future!
What to expect in Sweep City:

Cruise through a sci-fi city in your street sweeper cleaning up road trash and muck
Fish weird treasures out of the trash
Help the locals (none of them are trying to eat you this time)
Get lost in the glow of street lamps on rain-soaked autumn streets
Trick out your sweeper with upgrades, custom paint jobs and cabin comfort
Chill to your own tunes with the in-cab music player while you work
We know this is a weird jump from horror. But sometimes you just want to make a game about cleaning up the future and finding gold fish in puddles.
Want to try it early? We're looking for playtesters! Or Already convinced? Chuck it on your wishlist:

P.S. The street sweeper's headlights are way brighter than the Flash Light ever was
