This game is great and is so well balanced that a simple concept is made into hours of playability. This and Furdemption have me convinced that these guys will always put out awesome, well thought out, challenging games and that they deserve to have far more people playing them than it seems are. Bottom line: get this game. It's free and feels like it shouldn't be. What more can you ask for?

This game is just perfect. There is nothing you can do to make it worse, so don't be afraid to expand! Add new enemies, levels, increase the level cap of upgrades, add more upgrades! I beat this game and can't stop playing it and want something new!

A perfectly made game, I thoroughly enjoyed it. I'm still playing it, trying to beat my own high scores! I highly recommend this to anyone who loves simple games with extreme playability and addictiveness :)

This game is so much fun I actually wish they would add the in app purchases back into the game so I can show my support lol. Thank you devs for a fun time that truly is free. I'd love to purchase a sequel!
