AMOEBA — Devour & Evolve

A single-celled arcade game on a microscope slide. Drag to grow a pseudopod and wrap it around whatever is smaller than you; hold on until its capture ring fills and it becomes part of you. Organisms flee, larger rivals hunt you, and your own mass bleeds away if you stop feeding — so you are always either growing or dissolving. Five evolution forms, an endless culture and a ladder of timed Trials.
