Very cool take on the theme! I loved the strategy element of the game, which was a bit like reverse tower defense - you started from the inner most levels of the tower with all the defenses, in some sense. However, I did notice that once I had built a couple of obstacles at a certain distance and which forced you to walk next to a vine tile every single time it turned night, the game was easy to beat because the werewolf could never make it in time to the gate. It was still fun trying the combos though. I would suggest that the plants would wither away after certain "uses" or the wolf gets cleverer (or stronger) as the game progresses so that nothing can hold him down for too long forcing you to re-strategize. Anyhow, nice game!
