i like the level variety.
didn't like the upgrades though. it's more fun to start with some skill set and expand on it (as you did) and buff up the original stuff and base stuff as well.
I thought this was a really cool and innovative game. I think what made it the most cool was how there were just so many different levels and ways to beat the game. I liked it how it seemed like no two levels were the same. The music was also fairly nice. It was especially satisfying when the rocks went back and hit your enemies! I thought it was just going to be like the same thing the entire game.
That really shows how much you care about putting variety in your games. The overall graphics were really nice too. I think my favorite level would have to be the third one. I just like how those guys die so easily and then fall to the ground when they're hit by their own rocks. It was hard to even tell this was a defense game as it was so unique.
Really really good, and addictive game. maybe more dramatic music during boss fight levels could have been better: more drama, more intensity..
Really great game ;)
Game is really fun and its nice to see a new original game.
