If you create a sequel to this game I suggest making the player control a entire party of players which gather equipment and stats individually. Example: At early levels all characters are the same but by the end the player has made "classes" for each with their picks of who gets what.
Anyways great game even though I died on the final boss T.T
very good game got me addicted for a while :)
Only problems i encountered was the damage numbers not being accurate and i thought there was too much grinding for all of the challenges etc.
