At first, I thought it was just the typical the-big-eat-the-small game and got a bit bored out. But it wasn't, the dialogue was deep, it changed my mind around, and in truth, it was more than a game, it was a microbiological world happening before you.
Deep, beautiful, and the pacing is decent to let the story sink in. If possible, can I ask if you animate the cell by sprites or by procedural animation? They look quite realistic.
