Breakout 71 - Open source game

Control the paddle by keeping your finger pressed. Break all bricks to finish the level. Chose an upgrade and play the next level. Try to catch all coins, never miss a brick, and clear levels quickly to upgrade better and faster. Many upgrades increase the "combo", a number shown on your paddle, which determines how many coins are dropped when you break a brick.

This game is open source, ad free, does not track you, and works offline. It is under 1MB and should run smoothly on old android devices. There's also a web version you can use without installing anything.
