It's a solid entry that does a lot of things well, and I agree with the criticisms and suggestions made below. I would have been more motivated to continue searching for fragments if 1) getting to and from the gem gate were easier and 2) the fragments were visible on the map (at least at some point). Good work!
Also, I might be in the minority but I thought the music was a little *too* serene. Didn't feel like it quite matched the gameplay of dodging blades and destroying bugs.
