I/O is a minimalist but deeply strategic puzzle-arcade game where every bounce matters — and one wrong move could end your run. At its core, I/O is about survival. You bounce between two platforms filled with numbered cells. Each bounce reduces a cell’s value — and if you ever land on a cell showing zero , it’s game over. Unless… you’ve got a power to save you. 🧠 Plan Your Moves. Adapt Fast. Each run presents a fresh grid and unique challenge. Think ahead, redistribute cell values, and use your limited powers wisely. Every 5 stages, you’ll enter Split Mode — a tactical break where you can transfer half the value of one cell into another, giving you a chance to balance the board and extend your life. 🧬 Choose Your Powers Before each run, pick two powers to bring with you. These are game-changers: Safe Bounce : Survive a 0 hit once. Value Boost : Double the value of a cell. Overcharge : Double your score for one bounce. Zero Cleanse : Turn a 0 into something usable. And more... Each power has limited uses, so timing is everything. 📈 Progress & Unlock Earn score by surviving longer and bouncing smart. Use that score to unlock new power-ups in the Power Store , giving you more tools and strategies for future runs. 🧩 Key Features Endless, score-based gameplay focused on strategy and adaptation Power-up system with 8+ unique abilities Split Mode for mid-run cell value redistribution Clean, responsive visual design Strategic layer that rewards planning and risk management Steam support and progression tracking Highly replayable with new combinations and runs each time How long can you stay in the loop?
