Could use some enchancements.
First off you should Give us maybe 4 sets of 10 questions because going through 40 questions isn't fun and one of the questions are wrong because i answered it right you better recheck your facts.Also instead of just saying wrong or right you should tell us what the right answer was after each wrong answer we give so we can "learn" something.I am a diehard dbz fan and even though every single game to date has been crappy just trying to take advantage of the huge dbz market just putting out crappy games except Tenchika that might be something else...
But anyways you should probably make a minigame if we get all 10 right and you should rack up points based on how many you get right.Like 3 in a row gives you +10% more points and etc and like if you get the last question right you get double the points you got for the other questions you got right.These are just some ideas i'm throwing out from the top of my head.Be creative~
