This game was pretty cool. The art was cute. Machine gun shot a bit too much so it looked like a hose or something as the bullets were a solid line. Also, it crashed at level 4 or 5. Once I got the machine gun, I felt a little overpowered. I could just "hose" them down and everything would die pretty quickly. But with polish, I think you could get it a bit more balanced out. Another change might be to format the upgrades a bit differently so they're easier to read, like put each in a large button with the text or something. I appreciated the indicators telling me where stuff was so I made sure to collect it all before going to the next level. Overall it was a fun game. Well done!
