I beat the game and here a some things you should fix:
-When you finish a battle, it takes forever to award all the XP, especially after the final battle, (3000+ Xp) You should be able to click and skip the process.
-In then ending screen, it said my record was 0 Wins, 49 Losses. Even though my real record was 49 Wins, 0 Losses, not to mention I won the last fight...
-And yes, battle needs at least x2 speed.
-And when you select the first upgrade along the "assassin line" it automatically awards you the next upgrade to the left branch and makes you spend 7 ability points. It made me go into negative ability points.
-The Training mood items dont work.
-when finishing training, the ABI and MOOD box have no function.
