I would always go to the next checkpoint, killing as much as I could on the way, and then when I got to the blocked point I would just wait until the next full moon. Then it was a game of me wasting days until then. I feared I'd overlevel o_o My time balance was totally awful in this thing D:

I have to say the finale of this game is awesome. The final battle took me over 40 minutes to complete. And the design of the final boss was sexy incarnate.
