Yeah, there isn't a ton of combat-related content, but there are actually different types of snake-enemies that are supposed spawn when it turns night-time. I guess they just decided not to show up in your game, so... uh... I guess you got a peaceful world. Whether that's a good thing or not is up to you, I dunno. :P
Anyyways, thanks for the support, and I'm glad you enjoyed the game! (Despite the slight technical bugs *features*.)
