Quite nice. Conceptualy it is very accomplished and contains a grain of actual educational relevance. As for constructive feedback: More consistency in visual apperance, line thickness, charater design, color-/lightlevel-difference between background and interactable elements, ect. would increase quality. I found the earlygame a little slow and awkward, maybe a bit higher turnspeed and a way to dodge "warrior bacteria" had made the first few levels more pleasurable.
Overall a very nice entry!
