first of all,i thought you didnt know how to make games on linux ubuntu(unless you are making the game on windows,lol)anyway,if you want the game to be really awesome,you need BOTH a story mode and free mode(story mode is a side scrolling "adventure",and free mode is like super smash bros,you pick some characters and fight with them.)and,of course,options.also,you could add weapons,swords,and cool stuff like that,and you should be allowed to create characters,too. if this was confusing,tell me and i can make it into a list,i am known for confusing people XD.
