My Christmas special build/mini-game !

I told you all something big was coming...

Well, here is a small, humble present.

Just spawn it and look at its animation, no need to touch the controls.
I just spent like 5 days making this, soooo please consider playing the game ; here is a clue :

There's a gift in this present box.

Its name will give you access to something big...

Hint #2 : You don't actually need to use the build in the sandbox.

Also, disclaimer : you need the Overload mod to use this opresent as intended.

The build itself is kinda useless, but the treasure it hides isn't.

Disclaimer #2 : this build, as a mini-game, is intended to be seen by the largest ammount of people possible. Spread the word, the first 10 users to find the surprise will get their names written on this post !

Also, if you liked the game, maybe consider leaving a small updoot ? :)))
Last but not least, any feedback is much appreciated !

Small warning : for all of you who didn't find the surprise, don't worry. I'll release it publicly in a week, for the New Year. A good way to start 2021 :D
