About
"Npc Problems: Vertex Coloring" is a minimalistic puzzle game based on a real computational problem, where you solve handcrafted instances of the NP-complete vertex coloring problem. The goal is to color the linked circles in a graph with the minimum number of colors, without having any two connected circles share the same color. The game features a relaxing neon graphics environment and original synthwave music. Note that this problem is NP-complete, meaning it could take modern computers years to solve, depending on the size of the problem.

- The game features a unique and clever puzzle concept that is both fun and engaging.
- It allows players to progress at their own pace without the pressure of a timer, making it a relaxing experience.
- The colorful graphics and pleasant background music enhance the overall enjoyment of the game.
- The game is very short with only 32 levels, which may leave players wanting more content.
- Some puzzles can become repetitive and too easy, especially for seasoned puzzle enthusiasts.
- Restarting a puzzle from the beginning after a wrong move can be frustrating and disrupts the flow of gameplay.
