Well, here is a little review about your level. :-)
I played as Spaz at Normal difficulty, and I quit after getting stuck at the part with the construction bars with all the dragons on it, and the blocked access to the next building right of there…
Eye Candy: 87%
I think the eye candy is nice. The only real flaw in Eye Candy I saw were the poles at the side of Nick’s Cafe’s doors. They were floating. O_o
Gameplay: 80%
I liked the gameplay too. The system where weapons served as ‘keys’ was pretty fun, but it forced me to use the blaster. But, the terrain was very nice.
Usage of enemies: 80%
The enemies were well placed, but some of the enemies didn’t suit in a city tileset at all, like the monkey and the dragons. Not too many nor too little enemies in the level.
Usage of items and weapons: 80%
The items and weapons are, like the enemies, not too many nor too little. Using weapons was wasting time, since I needed it to access certain areas.
Total rating = (87 + 80 + 80 + 80) / 4 = 81.75%
Nice first level post. :-)
