About Quantum Sleeper
"Operative, this is a priority alert. Research Facility G-1-6 has gone dark. Your mission: reestablish contact and investigate the communication blackout. You're equipped with standard-issue gear, including the AEGIS-scanner and a flashlight. Primary objective: restore comms with facility management. If that's not possible, retrieve all critical research data - it's highly classified. We expect regular status updates."

Stealth Gameplay: Avoid detection as you investigate the facility's secrets. Use sound and environmental cues to your advantage.

Recent verbatim reviews from Steam — separate from playze.io community reviews below.
Its a short game, but the mechanics are solid. You won't know what you're doing at times, but luckily the scanner colours things you can interact with in green. Wouldve loved this game to somehow be longer, although they'd have to fiddle with making the flashlight more useful; since the only time i used it was to check the nameplates of rooms3 found this helpful
I really enjoyed this game. A new type of experience and well-executed at that. Any chance of more I wonder?2 found this helpful
Very fun game, I'm a sucker for LIDAR games , honestly although removing the monster would've made it better, making it just the sounds would've acheived a similar goal, once you learn squat walking makings you 99% invisible (Don't walk into the guy) you tirvilize it anyways2 found this helpful
As one of the devs I hate to admit but I cant sit through an entire playt without taking a break. Creature just loves sneaking up on me. We love watching your streams and videos. We have made a lot of changes based on things we noticed or were suggested by you. We hope to continue this story and that this introduction has hooked you!2 found this helpful
So cool but I got to a point where I'd have to restart to progress. That thing kept spawning right next to me and killing me instantly every time I reloaded. But goddddddddddddddddddd I wish I could have the patience to start over, this game is INSANELY cool otherwise. Hope you all have better luck! --EDIT: After leaving this review, the developer reached out to address what I had no idea was an actual issue! I thought it was just bad luck! This game is 10000% worth the buy, especially since the dev CARES! But beyond that, they game play itself is really spooky and strangely gorgeous to experience. RECOMMEND 100%!!!! I'm gonna jump back in and enjoy every second of it! <31 found this helpful
This is Actually a Very well made game only issues i had with it is that I am too stupid to figure out where to go and how to not get killed by the enemy lurking within, I hope you all enjoy it even if I didnt.
