More gameplay. Those colored blocks (placeholder art) actually alter the attributes of the microbe you're inside, and changes propagate upward (to the parent, to the parent's parent, etc)! eg: Increasing microbe health increases their size, and the map itself.

Oh, and you have to be smaller than the thing you try to inject... so you can also change your size!

Gah, so much left to do! No shleep for me. Only 11 hours until submission! Need moar arts! More bubbles! Ability to possess enemies and play as them! INFECT THEM WITH SO MANY BACTERIOPHAGE, THEY E'SPLODE!

And... a win condition! That's probably important.

I should probably also consume nutrients or something.
