Okay...
Basically, here is the deal. You made a hack and slash, but lacking some main hack and slash rules.
The hero needs to have some tpye of large, kick ass weapon or power, or have an abnormally long reach.
The hero can attack while running / have a running attack.
The hero can jump.
The hero has a special power that can occasionally be used.
The hero also has to be customizable. Usually with weapons, name, looks, thats all it takes.
Also, you tried to insert a troop system. It was small scale and sort of lame, being that everything attacks so slow, and you have to constantly replenish them.
Another problem: EVERYTHING ATTACKS SO SLOW! It's ridiculous. There is no combo, no nothing, just tapping space and moving.
