fun game. I don't see why you have the camera move with the character. Would be a more smooth game if it just showed the entire level and did not move. I often found the camera moving and affecting my shots. I also found that it often showed mostly blank space to one side of the screen.
Most games if you get hit you become invincible for a short time. In this game, if you get it, you lose control of your character and get forced to hit whatever the next obstacle is as well.
I can beat 14 levels by running in circles over an hour and a half. Then, I get to spend 4 hours grinding level 10 before I get all of my previously useless companions until I max them out. Then I get to max out on runes and hope I win against the final boss. What an interesting game!
As I defeated the first boss on wave 30, believing I had won, I thought to myself, "Wow, this game is way too easy for a hard badge. I'm only half way through the upgrades." Then the epic boss battle started.
