I feel this could be improved in a different game however it dose not seem to work well in this format. ### 5/5 — Solid game, and makes science fun *2019-11-04* This game is well-designed and seems to capture some pretty sophisticated aspects of microbiology. Science aside, the game is simply a blast! And it's plenty challenging, which keeps things interesting. Highly recommended. ## Frequently asked questions about Phage Invaders ### What is the gameplay like in Phage Invaders?
