# Huevo — Color Sort Puzzle

> Mobile color-sort puzzle game by ten Bruggencate Development. Currently in closed beta; full Google Play release scheduled once beta feedback is integrated. Pay-off: "Sort. Relax. No stress." Built on Unity 6 in portrait orientation for Android (iOS planned post-beta), with an HMAC-signed online leaderboard hosted on tenbruggencatedevelopment.nl.

Huevo is an indie mobile game in the color-sort puzzle genre — pour colored balls between test-tube containers until every tube contains a single color. Levels are hand-curated across nine themed worlds, with both a relaxed Zen mode and a competitive Challenge mode.
