I understand your wishes with this game. However, I'm not into the habit of re-rolling a character every time something doesn't work. Especially when the full game comes out, if you expect people to do this, you will get a lot of refund requests. Unless you seriously change the way the game plays from the start, I doubt many will be enjoying this.
GOOD RPGs give you a blank slate. A character that YOU have to build through completing quests, challenges, and fights. Giving a character ~10 points to assign right off the bat, which is not earned in any way is pretty meh. And then when you go through the whole role picking part and questionnaire, I spent like 10 minutes reading and deciding which path to go down, you expect people to re-roll and do the same thing again when the first fight fails? I mean... how do you not understand that this is gonna turn people off?
I understand this is a combat demo. And I hope the full final game is more 'noob friendly' or you guys are going to have a lot of players turned away. Perhaps you can add difficulty settings like Easy, Normal, Difficult, and Hardcore. Like most games have. Then you can adjust the difficulty of the combat through that setting. Otherwise it's gonna be very hard for 'new' players to enjoy the game. RE-rolling 10 times to see what works and what doesn't, is not my idea of fun. Even though some will disagree.
Best of luck!
