Good...BUT
Real good man this is great stuff but if u do create a second one i suggest u add
-Add Sounds Or Music
-More Enemies
-Less Repetative
-Difficulty Settings
-More Maps
-More Tower Types
-Different Upgrade paths
-Instructions on the game
- A pause inbetween levels
- better graphics would be nice
Thats it if u added all that This would be a bad ass mutha freaking map so yah 5 and thats being geneours
