Huevo
Why Huevo sits in Labs
Huevo is one of our lab projects: a proof-piece of what one developer with AI as a development partner can deliver end-to-end. The visible layer is a Unity 6 mobile puzzle game — sort coloured balls into tubes until each tube holds a single colour, with the pay-off Sort. Relax. No stress. — but the technical backbone is what makes it a Lab: a custom HMAC-signed leaderboard backend on tenbruggencatedevelopment.nl, anti-cheat moderation through a dedicated ban table, and shared infrastructure coordinated across three repositories (game client, backend and landing page). The game is the surface; the engineering underneath is the real story.
Two ways to play
- Zen mode — no timer, no score, no counters. Just the puzzle, calm music and the player's own pace.
- Challenge mode — race the clock, build combos for score bonuses, earn huevos to spend in the shop.
Nine worlds, 200 levels
The campaign runs across nine worlds — The Nest, Coral Garden, Tidal Pools, Sunset Ridge, Aurora Cave, Rainbow Peak, Crystal Depths, Starfall Summit and Infinity — each with its own backgrounds and accent colours. 200 hand-curated levels grow from three to ten colours along a deliberate sawtooth difficulty curve so harder levels alternate with rest stops. Each world layers in new colours and deeper puzzles.
More ways to play
- Endless Mode — infinitely procedurally generated puzzles from 9 to 12 colours, with personal-best tracking.
- Daily Challenge — a date-seeded puzzle that's the same for everyone each day, +50 huevos reward.
- Weekly Challenge — three rotating challenges drawn from a pool of eight types, refreshed every week.
- Daily login streak — rewards consistent play.
Personalisable
Huevos earned in Challenge mode can be spent in a four-tab shop: 5 visual themes, 21 egg cosmetics (hats, accessories, shoes for the bouncing egg mascot), 10 marble styles for the balls, and 3 power-ups for trickier levels.
Accessible by design
- Colourblind mode with unique symbols on every ball — an independent verification layer on top of colour.
- One-handed play — the entire screen reachable with one thumb.
- Bilingual (Dutch + English) with a language picker on first launch.
- Privacy-friendly — no account required, progress stored locally via PlayerPrefs, no third-party trackers.
Engineering and quality
Huevo is built in Unity 6 (6000.3.11f1) with the URP 2D Renderer and the New Input System, in portrait orientation for Android and iOS. The visual theme is "Glassmorphism Night" — dark navy with purple and orange radial glows, animated background blobs and frosted-glass UI panels, all built atop a custom GlassUI helper.
The codebase has roughly 50 runtime scripts and runs through a custom validate.sh on every release (lint, code style, EditMode tests for level generation and data validation). Release versions are stamped via ./deploy.sh release which bumps the version in ProjectSettings and tags the git history.
Status
Huevo is currently in a closed beta phase, with a public release on the Google Play Store planned once balance, onboarding and performance on the target devices are fully tuned. Updates and any beta access run through the Huevo landing page.
