I basically put everybody on the list who posted here asking to be added there. xD
The main testing will work that way that you simply have to play the game. All error messages will be automatically logged, you can add comments on them. There will be additional testing jobs like excessive minigame testing, puzzle testing, etc. Unlike the beta test for the Final Demo, you will not have to rate bosses and dungeons yourself. There will be a logger which will log how many EXP you gained, how many gold you gained, how long it took you, how often you entered a room, how long it took you to solve puzzles, how many battles you had, how many battles you fled, how long it took you to kill the boss, which attacks the boss used, which attacks you used, how much damage you have done, how many items and which items you have used, etc. You can add a comment at the end of it and that's it.
