I had a lot of fun with this, and the mechanics were cool, but all the while I was longing for some kind of end-goal (e.g., a timer with a highscore similar to old arcades).
P.S. If you are looking for ideas to improve the game further after the jam, I was expecting a couple of tanks to appear and start shooting at me - they can just damage the biomass and clones to not add another bar.
