We like it in a group xd.
The concept is great however I feel it is missing some type of mechanics. It is even hard to say what type of mechanics. At this moment it is really about moving all units from one place to the other as quickly as possible, this way they can reproduce 'infinitely'.
Maybe adding a 'food resource' and very simple farming mechanics or picking up the food that spawns randomly would force the player to focus more on the surroundings? This way player would have something more to do than just reproducing the units :).
Still - even though the feedback may seem a bit negative - I really enjoyed the game. It was fun!
