oh 5 stars man good game

Heh
- Nice graphics
- Quite pacifist : no monsters... only little cute turtles and rats :D
- The music is nice, quite unfitting i d say but.. well keep it :D

Well indeed it gets boring after a while, but its not an easy thing to change
Either you put an end to the game after like wave 20
Or you nearly double the content : you add different enemies that i dunno like together, not just fall down.. maybe you add upgrades with another sting IA controlled that shoot other fruits :D

Also, with such music, I imagine something more white, more loungy, more round. Take a look at other games that work with bacteria eating others and growing. Its quite white and loungy also, but the mix loungy atmosphere and loungy (jazzy so) has a better integration than in your game. Maybe take some graphic effects from their games..

Ah yeah something to fix :
Since the sling is close to the bottom of the screen , often i misclick outside the flash window. Then game becomes paused. Maybe add more depth in the bottom to avoid that.

Hope it helps ! :D Contact me for ideas if you want ! GL

this game gets boring after couple of seconds.

I didn't think much of this game until I found that when I play again it's NOT from the beginning. It's quite a cute diversion :) But I see two main drawbacks:
1. Instructions aren't too clear. When I unlocked a new weapon, I was defeated very quickly b/c the game didn't mention pressing X to detonate, only the Author Comments - which also refer to "the last two fruits" while omitting how many fruits there are overall...
2. The game becomes difficult to control and buggy during the later waves, when I shoot quickly. It gets confused if I shoot before the next fruit appears in the sling, if I shoot before detonating the previous fruit, and it becomes worse when switching weapons.

Fix these and the game would be really good. Throw in purchasable upgrades - e.g. recharge rate, healing rate, detonate-on-hit, maybe something to deal with these pesky turtles - and achievements, and Sling Defense 2 should then be a hit! :)

A bit boring at first, but fun and strangely addicting after a while. Good job!
