Funny how most people don't have any problems with the game, because they read the dialogue when being given tasks or talking to characters. None of what you're describing as bugs are actually bugs.
Generally speaking, people are generally more likely to politely answer your questions if you post them without being a jerk. As it is, I'm bored enough to tell you anyway, since you've written the game off.
Everything currently available happens naturally through playing the game, and anything that seems like you can't get it yet or increase it yet is either at cap for the current release, or you didn't read the dialogue around when you were first guided toward it. I never needed to edit any variables. This is not a grinding game with huge stat requirements. You can only raise stats a few times in the current release, and that only serves to move the plot along.
Current stat caps:
- Strength 4
- Agility 4
- Endurance 4
- Martial Arts 3
- Magic Power 2
- Demon Power 5
- Fame 0
- Adventurer Rank E
As for the Veins Opening Potion, if you're at Magic Power 2, you're already at cap, and you crafted it a long time ago, and don't need to make more. Or you edited your stats, skipping almost all the events that are actually necessary to advance the story and see further events.
