Stick Warfare ideas

Well I have a lot ready for my game but I wanted to post a thread about ideas for it and to tell what it is about. SOOOoo.. its viewpoint is like that of terraria (if you have played it you will know what I mean) player in middle of screen, the base of the game is progressing through by defeating the various bosses, its not open world but there will be a lot of different maps to travel to including a semi open world thing (if I can get it to work properly) theres a lot of weapons you can get and stuff you can craft, chests to find, keys for doors/chests, there will be normle enemys you can fight or just run from, you can increase your health by crafting or finding hearts, there will be an ongoing story leading up to why the bosses are trying to kill you. theres a lot more I cant remember but that's the basics, tell me what you think, or what I should do or not do. if you like this idea and wish to help... THEN PLEASE DO! I would love any help, specifically with sprites for weapons and stuff as my 3ds's screen is partly broken making it hard for me to make them. (I can code fine though) at this point its fairly-not finished it was close to a demo but my friends 3ds broke with all the info so we lost a lot. tell me what you think.
