I made a Lock system and a Rebirth system for your base/player. The lock system is fairly simple, but the Rebirth has more depth. It includes different requirements to be met when you can rebirth. In the rebirth menu, it shows that you must have a certain amount of money and 2 specific fluffs in your base.

After rebirthing, it would give you 1 extra slot to put another fluff in your base, 20K money, more base lock time and a +0.1 multiplier on your passive income from fluffs.

This is a Verse UI shop system I made. It includes a free map that spawns in front of your base, different player boosts like the speed boost and jump boost and different slaps that have a better slap than the default one.
All the prices can be changed for the button texts as well.

The Fluffs can be purchased throughout the map. The Fluffs are shown by them hopping around the map. Through verse, I coded the animation that would play and had a button device follow the fluff. The text is a simple material that is over a plane object.

Materials can be gathered throughout the map as well. With the materials, you can go back and sell them for more money.

Also, in your base, you can collect your passive income from the fluffs and sell them.

You can steal other players’ fluffs from their base, but if you slap them, you can stop them from stealing.

I used the Carryable device to make it look like you’re stealing something. The slap pillow is a vfx that is attached to the player and the slap logic is through Verse.
