I've played this one before but this time I really spent some time on it. I felt like I did pretty good but I don't know maybe I'm terrible. I guess that's part of good game design though. I felt accomplished and successful after only maybe 15 minutes and still wanted to get better. It can get pretty hectic after multiple enemies start appearing in the same tunnel as you so you have to try to utilize those rocks to wipe them out at once instead of the trusty pump and pop method. If you see it give it a try though it isn't a standard arcade game.
