I just beat the game, I enjoyed the game overall. However, the endgame quest somewhat put the pacing of the final confrontation to a grinding halt. I would maybe would do have of the amount of Skystone or save the rest for a bonus room where talk about your experience with the game.
Just a quick update on this, the new 2.0 version requires 5 fewer Skystones, to speed things up. Thank you again for your helpful insight!
For now, they have been pulled while I consider how to best add a completionist bonus . I really like your idea, so in a future release I plan to bring them back in. Speeding things up took top priority for 2.0. I played a full, regular speed playthrough after your comments and realized you were quite right, the final quest needed speeding up.
