I beat the game with Armor-8 Magic-7 (almost enough xp for 8) and Attack-6. Then I spent another hour grinding xp to get my attack level to 8! So those last 2 sword levels are not worth it unless you're really having trouble beating the last boss or you just want to see what the strongest sword looks like. And want the title "Ultimate Master of Ultimate Destiny" :)
There's something wrong with the game balance when it's almost impossible to lose and I have only purchased 93 of 152 upgrades... After 42 minutes I just let myself die out of boredom and bought the rest of the upgrades with cash to spare. http://i.imgur.com/XiODW5V.png
The typing challenge thing doesn't move to the next line when you get to the part about hacking. "It takes the fun" and then it should move to the next line, but it doesn't, so you can't complete the speed test. :(
Hi! The problem should be fixed in ver.1669. I really apologize for the inconvenience!
