Hi guys! This is Sai Hou, one of the devs behind Facility X13. Over the course of just 3 months, our team came up with the idea from scratch, went through multiple iterations and painstakingly designed the levels.

We think we have made an awesome game, but why trust a biased opinion? :P Feel free to download the game and try it for yourselves. After all, it's free! But you know what else is free? Leaving us a 5-star rating (Right panel->Rate this game) if you liked the game. :) Whether you enjoyed it or not, we would love to hear your opinion, so do drop us a comment if you're up for it!

Thank you!
