Thank you!! And i plan to go juicier but don't want to overdo it either! xD
As far as the music -was running short on time and wanted to make a quick song that kept the beat without it fighting for attention over the large amount of sound effects I knew were going to be happening simultaneously.
To respond about the gun and how it works with the theme: the gun exists to help you reach zombies you couldn't reach without breaking your combo (which is also why it's very relevant to the don't stop theme -as it's target shooting under the pressure of maintaining combos to reach the goals. Some levels have zombies placed in more difficult ways that shooting them makes a big difference (also shooting them gives you a much larger score)
Oh! Also I loooove your idea for heavy knockback/fire to increase spin -that's great -i'm definitely going to try that! Anyway, thanks again for your awesome feedback and kind words! :D
