What the developers have to say:

Why Early Access?

“Early Access gives us the opportunity to shape the game alongside a passionate community. While the core mechanics and gameplay loop are already in place, we believe player feedback is essential for refining balance, adding meaningful content, and improving overall quality. By involving players early, we can ensure the game grows in a direction that resonates with those who enjoy it most.”

Approximately how long will this game be in Early Access?

“We currently expect the game to remain in Early Access for several months. However, this timeline is flexible and will depend on the feedback we receive and the scope of changes or additions we choose to implement. Our focus is on quality and making sure the game feels complete and satisfying for our players.”

How is the full version planned to differ from the Early Access version?

“The full version is planned to include expanded content, such as additional power-ups, new gameplay variations, visual improvements, and enhanced user experience elements. We also aim to add features inspired directly by community feedback. While the core gameplay will remain intact, the final version will be more polished, more diverse in terms of mechanics and visuals, and better tuned based on player input.”

What is the current state of the Early Access version?

“The Early Access version of the game is fully playable and includes the core gameplay loop, all main features, and a complete set of mechanics. Players can experience the full progression system, several power-ups, and the core challenge of the game. However, we're still actively refining balance, improving visual polish, adding quality-of-life features, and incorporating more content based on community feedback.”

Will the game be priced differently during and after Early Access?

“No, we do not currently plan to change the price after Early Access. The price will remain the same throughout development and after the full release.”

How are you planning on involving the Community in your development process?

“Community involvement is a central part of our Early Access plan. We’re looking forward to engaging with players to shape the future of the game together. We'll be collecting feedback on gameplay balance, new feature suggestions, and usability improvements. Players can share their thoughts with us via our Steam Community forums and Discord server, where we’ll regularly run polls, share development updates, and host feedback sessions.

Your input will directly influence future content, gameplay tuning, and even new power-up ideas or mechanics. Our goal is to build a game that grows in the direction players are most excited about.”

About This Game

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
