A game with a nice idea. I think that the game would benefit from having the vampire regen his health when he is in the shadows, as the timing can feel a bit harsh. It is a nice base to expand upon. Congrats for the entry!
Yeah, I agree with you on that. Actually, there is a "hidden" (didn't have time to make a tutorial) mechanic in the game for regen: when a plant is fully grown it is too big to be picked up, but the shade is so strong that you actually regenerate health while in it :)
