Part game, part visual experiment, and originally prototyped at the global game jam 2013, 577Rhea is the latest from André Sier, Portuguese artist-programmer at s373.net/x. You are your planet's last hope and you have to time-travel through black holes with primordial essences to prevent the inevitable collapse of your home. Aim for the blinking orbs which when collected, before time runs out, activate the portal to the next level. 25 levels included, soon to be expanded to 100+.
