Square Inertia

Square Inertia is a time-trial game where you control a fast-moving square through 50 levels. Each level has five coins, and collecting three opens the green goal point so you can finish. Your times are recorded as personal bests.

Movement and time trials

Use the square’s speed, slamming, wall-jumping and level-specific mechanics to cross each course and improve your times. You can race against a ghost of your personal best or watch your replays independently. Replays are primarily input-based, with some positional guidance to reduce performance variances.

Coins and colors

Collecting every coin and setting fast times while doing so unlocks alternate colors for the square. The levels are grouped in sets of 25. For each set, collecting all 125 coins unlocks five colors, while beating all 25 author times unlocks another five.
