I have a simple yet engaging word-card game concept ready to be turned into a colourful, polished app that runs on both iOS and Android. The core loop is straightforward: a deck of word cards is shuffled, a visible countdown begins, and players race the clock to form words before time expires. Here is what I need built: • A reliable shuffling mechanic that guarantees a fresh, truly random order each round. • A configurable countdown timer (default 60 s) that starts automatically once the first card appears, pauses when required, and resets cleanly between rounds. • A vibrant, playful interface—bold colours, smooth transitions, crisp typography—that feels right at home on modern phones and tablets. • Basic audio cues for shuffle, timer start/finish, and round completion. • Simple scoring and round-summary screens. • Store-ready builds for both Apple App Store and Google Play, plus all project source files. Acceptance criteria: – Cards never repeat within the same round until a reshuffle. – Timer accuracy within one second on current iOS and Android versions. – No crashes during TestFlight or Play Console internal testing. – Visual style matches the colourful mock-ups I will supply. I will provide the complete word list, sample art references, and any copy required. Unity, Flutter, or another cross-platform framework is fine—choose whichever lets you ship to both stores efficiently. Propose your development timeline and any milestone breakdown you find workable, and we can get started right away.
