Fairly interesting
I liked this game because it was very challenging. Of course, I also probably didn't like it as much as I could have also because it was so challenging. There were simply so many of these rocks that could so easily kill you! It's still an innovative game, but I would suggest making the levels easier. I know that sounds whiney, but you can simply have the levels start off easier and then go to harder ones. I also really admire the graphics.
What was also cool about this was how well the sounds synched with everything. It really gives you the idea of being trapped in this world. It's amazing how easy it is to blow stuff up. At least there's a lot of room for you to go around and explore. It's annoying how you lose a bunch of jewels when you die.
