There is little doubt that Microsoft's employees spend some of their free time making new and crazy apps. Many of these fall under the Garage apps rubric and are made in their own time. Whether or not FYCPT is that kind of game or not, we are not sure, but it does look interesting.
Unfortunately, the game is a private beta app so it cannot be downloaded, but we can see some screenshots from the artistically creative game. More importantly, FYCPT looks to utilize the Microsoft Band to control the main character's motion, which is something we have seen other devs do before on the Store.
The unlisted and hidden game was spotted by WalkingCat (@h0x0d) on Twitter.
Not much is known about FYCPT (including what that even stands for) although the description does say the following:
"Play as a cute paint drop character through dangerous obstacles and challenges."
Other than that not much is known about the 22MB game expect that we can't get it. Perhaps this is just an experiment and it will never see the light of day, but like HoloLens the Microsoft Band could have many ancillary functions including gaming.
For now, you can just check out the screenshots or view the game in the Store.
