Well with the anvil for example, sometimes it would properly block an enemy and sometimes they would go into it. Also it was hard to figure out at which distance an enemy could hit you and you could hit them so that a strategy could be developed to overcome that obstacle. But hey don't worry too much about it, this game has shown you guys are capable of being great game creators and with programming, that's something everyone struggles with (take it from a sophomore computer science student believe me i'm still terrible at it) but it's something you can improve over time by practicing to think logically about how each line affects what you'll see on screen. It's more or less being able to fix the smallest bugs by dividing the work in smaller tasks because usually, that's what causes the biggest issues. But anyways, congrats on your work and merry christmas!
