Librerama

Libre (from French, meaning free); rama (part of fliperama, from Portuguese, meaning arcade).

Librerama is an arcade compilation of very small, fast-paced mini-games (nicknamed "nanogames"), with the main objective being to rack up the highest score possible by winning the most nanogames you can before getting a game over, while they progressively increase in both speed and difficulty.

Features

 * 21 mini-games
 * Custom mini-games (See for a tutorial on how to create custom nanogames)
