Lots of flaws made the game nor really entertaining.
- Graphics and musics
- No bugs/glitches
- Simple gameplay
- Appropriate/moderate difficulty (It's strange that most people in the review section say it's either too hard or too easy...)
Cons (long list):
- Lack of defense diversity
- Lack of HOT KEYS
- Boring after a while
- Enemies killed outside the screen (before they enter the game area) will drop money there which can't be collect by the player, thus making the next waves harder. This can be avoided by not placing towers near the entrance...
- Calling waves early does NOT give the player extra resources... which is sad. It would help a lot on last levels.
