This was a whole lot of fun and a clever use of the theme. I played through several times because I was enjoying it so much. I managed to get three different endings and all but three of the achievements.
Your options menu was really nice. I liked that you could add addition buttons for clicking. The ability to ignore the timer was a really nice way to let people play around without feeling rushed, as was the option to mark unused pieces. The dev timer was also fun to give myself in extra challenge.
The art and SFX worked really well for the game. The shapes of the pieces were clear, which made it easier to plan things quickly before moving anything. I loved the names of the items. Part of the fun of replaying was seeing all the different names you had.
I would have loved for it to have been a little longer, because it was such a fun game.
