20-Level Android Hypercasual Puzzle

This project covers the full build of a hyper-casual puzzle game for Android, structured across 20 bite-sized levels. Gameplay should revolve around a single-tap or swipe mechanic that players can understand in seconds but still find progressively challenging. I envision bright, cartoonish visuals—clean lines, lively colors, and playful character or object animations that instantly read well on mid-range devices.

Core scope
• Design concise puzzle mechanics, then scale them logically so each new level introduces a fresh twist without adding complex rules.
• Create all 20 levels, balanced for difficulty and session length (under one minute for early stages, up to two minutes for later ones).
• Produce lightweight cartoon-style art assets and UI that match current hyper-casual trends.
• Build and compile the game for Android, ensuring smooth performance on devices running Android 8.0 and up.
• Include basic audio cues and a looping background track that fit the energetic, casual mood.
• Provide an ad-ready framework (Unity Ads or AdMob) that can be toggled on or off.

Acceptance criteria
1. A signed .apk plus full Unity (or equivalent) project folder delivered.
2. All 20 levels accessible through progression or a debug menu.
3. Average frame rate ≥ 60 fps on a mid-tier Android test device.
4. No crashes or soft locks in a 30-minute continuous play test.
5. Art, audio, and UI are entirely license-cleared or original.
