This was pretty good. One thing I might suggest is when I would finish a level the spacebar also acted as a selection button so I ended up restarting a few times when I did not mean to.
This game was fun I had a little bit of a hard time seeing where my pieces were going to land once my tower starting going up. Other than that good job!
I enjoyed the music for this however I am unsure of how to play it, and there was only text that says gold. A tutorial of some sort would go a long way!
