Great game! I hope a 3rd is on the way, or being thought of as we speak. It has real potential to be a console or larger game. From one dev to another, there are 3 things you really want to include if you want it to hit big time.
1. A much larger armory, more quests, different students, Basically a more factor. The more new things there are, the more it holds the players attention. (More levels! 30 is a very small number.)
2. The title screen was beautifully done. Cut scenes, cosmetics, continue the beautiful 8 bit artwork. Whats a little lack luster, the combat is VERY simple. A larger skill base, as well as possibly 2 different ultimates, would certainly spice it up.
3. Make the game multiplayer! A PvP option would bring sooo many more gamers its unreal. Make it real time, add leagues (bronze, silver, gold, Ivy) When players can play with each other, or smash on other players, the competition keeps the game alive a lot longer than other games.
Just some Suggestions
