Good evening.
I played it, but it didn't quite click with me. There's nothing to strive for (when you aim to get the central ability, there's something appealing about that).
Thank you.
Maybe someone has come up with a mod for 8 skills and levels, without changing anything else.
The central skill is overrated, and the game is still interesting without it. At the very least, the developers should have added 2 hero classes in the original game, to provide more diverse and predictable progression.
