About this game

AstroDiner Manager is a simple, fast-paced Diner management game.  You thought buying a cheap diner on a remote asteroid was a "steal." Well, after crashing your ship into it, you’re officially stuck. But a crash landing won't stop a true entrepreneur!  Now you’re part of it. Activate your Diner and get ready to meet your new alien friends. 
Order food and drinks, prepare dishes, mix cocktails, and do everything to keep your clients happy and satisfied. Fast and quality customer service is the key to your Diner's prosperity.  

Perform upgrades for your Diner to unlock more seats, new recipes, and new order types to fulfill your clients demands. Create a unique style, customise your interior with unique patterns and vibrant colors to create the most inviting stop-off in the sector.

Something isn't right about this rock. Why is there a diner here? What’s behind that humming, locked door? Befriend local slimes, complete quests, and uncover a mystery hidden in the deep vacuum of space.

Can't go through it when crouched. Fixed: Grammar in some notification texts. Fixed: Talking to Green Slime.

    Hotfix 0.1.6.6.f.a

    Hey everyone. The new patch is here for some technical issues you've encountered during gameplay.What the fix:Green slime dialogue fix: There was a bug when you tried to talk to the green slime at the beginning of the game - it was breaking his behavior, and the slime started to behave in a weird way or even get stuck in one place or near the table. Bar Terminal fix: After you order anything it was a bug with the delivery countdown screen. After reaching 1 second timer, the screen won't turn off and is stuck until you restart the Bar terminal. As well as some screen switching issues while the delivery is in progress. Your feedback is invaluable for helping me improve the experience. If you run into any other bugs or issues, feel free to reach out via the community hubs or on Discord.Thank you for your support. OneUnit Games
