Recap 2 player co-op shoot ‘em up Main gameplay Player 1: Bacterium Player 2: Virus swarm Main gameplay Shoot immune cells and chemicals Evade obstacles Infest body cells Charge and use abilities

Design Revisions Changes Critique More interaction planned Implemented & Planned More interaction planned Merge to single character with shared controls Revival by other player or at checkpoint Fluid mechanics Bacterium can only rotate slowly NPCs are exposed to Brownian motion Fleshed out player movement and attack behaviour (see prototype) Critique Setting Immune system simulation Not enough co-op functionality

Physical Prototype Screen space approximated by hex field board Characters are LEGO bricks NPCs move from right to left instead of background scrolling by Round-based actions and enemy spawning Shooting precision (skill) is approximated by rolling dice Player movement very different between bacterium and virus swarm Enemy behaviour adjusted to fit biological counterparts
