This was cool, I liked it. At first I thought it was going to be too punishingly hard but the regenerating health rate felt just right and kept it fun. Great concept of invading a host at the micro level, and the pill boss was actually adorable, love when games have mostly gnarly enemies with one random cutey. All of the death animations were really impressive, especially the final boss' death animation, watching that was a very appropriate climax to the game.
