Hello folks! Last revision starts the 0.3 update cycle with raising active animal families limit from 8 to 100, resulting in possibility of simulating 600 active animals at once (from old limit of 48). Please remember that while it's possible, and Creatura is decently optimized even for it's beta stage - high animal counts can (and will) take toll on your CPU.
Performance improvments for high animal counts should be expected later in beta. Stay tuned for first amoebas and cellular lifeforms coming soon into Creatura, and get to overbreeding tanks now!
