AI Inspiration WorldWhat it is
KEEP UP! is a browser arcade game by itch.io user Pranay (pranaysuyash), with three modes on one page: Stack & Siege for tower stacking and defense, Castle Kickoff for castle football, and Siege Golf. The three modes share one coin balance. The art is cartoon-style, with castles getting knocked down. The author says the code, procedural art, synthesized audio and design iteration were done by Claude (Anthropic), using Claude Opus 5.5 in Claude Code with several parallel sub-agents. Some assets and audio come from Kenney's CC0 packs and are credited separately.
Who it's for: Players who want quick rounds on a phone and like having a few modes to switch between.
Before you start: Free to play in the browser. The author says you tap and swipe on a phone, or use the mouse or Space on a computer. The platform lists English, and the screenshots are in English. Whether coins and scores go online is not stated. No age rating is given.
