Whew, what a game this is, seriously KI, this game is practically all I do these days.
I don't want to ramble, so here I go!
It would be nice if we had a sort of Survival gamemode, where we host a match with a max of 3 friends, but, we fight AI,
Basically, we would be fighting almost every enemy and boss in the game, starting with Lost Souls, all the way to the 4 Morganthe battle, it would start saying "Wave 1: Lost Souls" then perhaps :Wave 2: Rattlebones and Dark Faries" then it would escalate from there.
There would also be a 5 life/continue system, whenever you get to 0 health, it would bring you back to full health and say "Continues Remaining: X" then at the fifth continue, you lose and are sent back to the Arena,
Couldn't forget about the young wizard being rewarded for his fighting, when you lose your last continue your reward is placed in the gift menu, to be later retrieved. If you lose at wave 2, you would get 50 gold (wave 2 so people couldn't just farm). If you complete the final wave, it would ask if you would rather have 25,000 gold or 2,500 crowns.
Just a pretty simple idea, but certainly one of the best ones I have.
