Planetarium is an experimental tiny-planet explorer and space survival game for the browser. Planets could either be designed from scratch or be carefully procedurally generated. Some of the gameplay related factors the game would handle would involve player progress, danger/difficulty, and purpose.
The challenge is to create aesthetically beautiful worlds while keeping a good framerate in the browser.

This first prototype focused on exploring the limits of optimization. Art is not the main focus here.

[Edit] There's a new prototype of this planet.
