Metroid Mod: Nightmare Boss Battle - Terraria (tModloader)

Edit: This mod is now available: https://forums.terraria.org/index.php... He's finally here... and before Christmas... I wonder if people will believe me when I tell them I made Nightmare before Christmas? Lol Nightmare was very interesting to make. It first started as porting him from Fusion, but I realized that his attacks in that game were incredibly basic, when you got right down to it. All he did in that game was move, shoot, and cause gravity distortion. The thing that made him difficult and somewhat terrifying was the way he moved and the design of the room he is in. All this is nearly impossible to replicate in a sandbox game. So, many changes were obviously made. The first thing I did was start taking notes and ideas from Metroid: Other M. Despite Other M not being exactly the greatest Metroid game, and its Nightmare battle lost a lot of the terrifying factor, there were some elements that clicked in and seemed to work rather well. I initially wanted his arms to swing back and forth, and possibly aim his lasers up and down, but that could've turned out goofy looking if I did it wrong. Eh, I think I did a pretty good job... But of course there is still some balancing that needs to be done before he can be called "complete". Comments and suggestions are welcome. And although I may not reply to many comments, I still try to read as many as I can to get feedback. Gravity orb sprites were taken from W1K's version of Nightmare, so credit to him. Also the sprite for the summon item is taken from W1K's as well. Terraria and Metroid are owned by Re-Logic and Nintendo respectively.
