SteamYou are a robot.
Your mission is to bounce the ball. Again and again.
Reflect the ball exactly N times. Route it to the exit.
Do not think about why.
Arrange the pieces, build the logic, meet your quota.
Your job as a robot is to guide the ball launched from the blue portal into the orange portal. You cannot interfere with the ball directly — instead, place reflectors and other gimmicks to steer it toward the goal.
To clear a stage, count the ball until the number displayed at the top reaches zero.
Learn the properties of each gimmick and maximize your count as efficiently as possible. Don't worry — every time a new gimmick appears for the first time, there's a dedicated tutorial stage to introduce it. Each one is carefully crafted to ease you in :)
You can't touch the ball. Whether you clear the stage or not is decided entirely before the ball starts moving. No reflexes required — just the ability to read the space and the patience to engineer the perfect chain reaction.
This game also has hidden elements. Don't give up until the very end!
Good luck!!
