Really interesting concept! It was a bit challenging at first, but once I got the hang of the mechanics, it became very engaging. I managed to finish the whole thing! The cell simulator idea with upgrades and resource gathering is solid. One suggestion for improvement: currently, it feels like 'one vs everyone' because enemies only target the player and projectiles pass through them. It would be awesome if enemies could fight each other too! The art style is unique and fits the vibe well. Great job!
