Guide falling photons into matching colored collectors. Create gravity wells to bend their trajectory!
Touch anywhere and hold to create a gravity well that pulls photons.
Slide to move the well. Position it to curve photon paths into matching colors.
Don't let energy hit 0%. Catch photons to recharge. Wrong colors drain energy.
Left-click and hold to create a gravity well that attracts photons.
Drag to position the well. Guide photons to their matching collectors.
Keep energy above 0%. Correct matches recharge, misses drain energy.
