Squarescape is pure retro gaming glory. This festival of pixel art is a worthwhile centerpiece for any puzzle app collection.
No free roam controls to be found in this app. With each movement, your square gets launched in your chosen direction until it hits a wall. You'll have to bounce around between obstacles to navigate through the levels.
There's more to the puzzles than simply traveling from start to finish. Each level contains one ball, and only after you've collected the ball are you able to escape through the exit. A smattering of special obstacles -- like the gray Xs -- makes things even spicier. Bump into one of those and it's back to the start with you!
