About this game

Move. Calculate. Survive.
Stellar Protocol is a grid-based puzzle game where every move counts.
Guide your unit through 99 increasingly dangerous levels
and learn the rules of each new threat by facing them yourself.

THINK BEFORE YOU MOVE
Every level has a move limit. Rushing leads to failure.
Study the board, understand what each block does
and find the path that no one told you about.

DISCOVER, DON'T BE TOLD
Each stage introduces new blocks with their own behavior.
No manual. No spoilers.
The more levels you clear, the more you'll understand
and the more dangerous things become.

THREE STRIKES
You have 3 attempts per run. Each failure deducts from your score.
Reach 3 failures and it's Game Over — your score is locked in history.
CHASE THE OPTIMAL PATH
Clear levels on the first attempt with the fewest moves possible
to unlock maximum score bonuses.
Can you achieve a perfect run across all 99 levels?
TRACK YOUR LEGACY
Every run is recorded. Your highest-scoring clears are saved to history
and an All Clear of all 99 levels is marked in gold, forever.
99 hand-crafted puzzle levels
New block mechanics introduced throughout the game
Move-limit scoring system with optimal path bonuses
Full gamepad support
Persistent score history with All Clear recognition
