Dismantled about 10 pieces. Level didn't change, no new content got unlocked, so I quit.
Thanks for playing Screwing Around & detailing your play experience, I appreciate it! :)
Should the game eventually get a full release I will attempt to commemorate your achievement with the "Dismantled Ten Pieces, Got Nothing! 'Intonaco' Memorial Award" in-game achievement as compensation for, well... getting nothing in return for your efforts this time around. :D
Unfortunately as you discovered I didn't manage to implement the progression system before the deadline so all the content is unlocked from the beginning of the game. I realize this does not make compelling game play. :)
Thanks again for playing & for not giving up after nine pieces!
