Fun incremental growth game.
I like how the viruses are cute little guys while the cells look like an animated biology textbook. It works together well to give it personality, but also a realistic vibe.
Some music would be nice but the sound effects were good.
The ending was a bit anti-climactic and it might have been fun to see a cataclysmic failure of the host or fight against an immune system but these are both reasonable limitations for game jam scope.
Overall an enjoyable game jam entry
