that's a valid direction too i think! What i cal 'toy-ish' is the simulation aspect: placing things and seeing how they evolve. Kind of Game of Life i guess. Be it more about the curiosity of making things interact.
But again that's one direction! I thing going for objectives with complex combinations can be great too! Just that again, as it is right now if find it hard to establish a stratégy involving more that 2 or 3 rabbits. But maybe i'm just bad ahah
