Positivity play online

This app was inspired by "the dollar game", a mathematical game described by the youtube channel numberphile: https://www.youtube.com/watch?v=U33dsEcKgeQ&t=495s

Tap on a node to transfer 1 of its score to all connected nodes.
The objective is to have all nodes with a positive score (0 or more).

The levels are procedurally generated.
Every time you win, the challenge will increase and an harder level will be proposed to you.
Via the settings you can immediately jump to a harder or easier level.

Each level is guaranteed to be solvable and you have an unlimited amount of moves to try your best and have a chilly, relaxed experience.

Good luck!
