The idea of combining gloomy b/w depressed princes with vibrant animal minigames is lovely. The overall esthetics works nicely together.
I would like to have some point to the minigames. Highscore maybe? With the fish before understanding the controls it ended. With the ants the pheromone trails are brilliant. But again some goal would be nice. And as was mentioned in the other comment, I have no idea if the reincarnation is time based, or if I need to do something.
