There's an interface bug where the reward screen consistently says you receive one more coin than you actually do. Nothing game-breaking, just a bit odd.
The fact that it is physically impossible to win the game at max upgrades without collecting 5 or 6 fuel pickups is a sign that the balance is screwed up somewhere.
NEEDS
A RESET
UPGRADES
BUTTON
I cannot stress this enough. A "Reset Upgrades" button will help to fix the balance issues, and make it easier to try different play styles.
When I cast Cleanse on a Slime-d ally, the status effect disappeared (and I could control them again) but they still look like a slime, and disappear instead of running the attack animation.
The grading system was a bit confusing - the first time through, I killed about half the guests and took about 15 minutes, and the second time, I killed maybe 9 guests and took about 6 minutes, and I got a C both times. Other than that, I enjoyed it a lot. Scaring people never gets old. >:)
Nothing particularly original (I've seen many, MANY games with this style of gameplay), but well-executed, looks nice, and is pretty functional. Good work.
Very well created. Reminds me of the old Raiden arcade games. Only real complaint: can't see regular enemy health bars, and the boss bar isn't as noticable as it could be.
The bonus zones are only available on Challenging and Heroic. If you beat either one, Zone 6 opens up, and if you get the "Legend" achievement (beat the Mayor on Heroic w/ no training fights), Zone 7 opens up.

Good catch, thanks! We'll fix it.
