OMFG
Graphics, sound, and music are amazing, but game-play sucks balls. Using the mouse, pulling it back and shooting the rocks fast still doesn't help when you're at waves 3-4 and hordes of cats are coming at you. It just ain't fun.
I lost primarily because the upgrade system was crappy and slow. I didn't make enough money to upgrade my slingshot within the first two levels. I felt discontented and a bit unhappy that i used the money (which I was trying to save up for upgrading my slingshot) to heal my wall after wave 3.
At wave 3, there were freakin' cats standing away from the wall and attacking with projectiles. I found my wall getting ruined by the projectile cats AND the normal cats attacking the wall with their paws at the same time. I can't kill both projectile cats and normal cats at the same time! They are both at different places! It's hard, especially when i am being pressured by so many cats to move my mouse faster. I can't fling my mouse that fast! that really sucks, dude.
You should make the upgrade system faster. For example, you can edit this game so that money is more easily acquired OR you can lower the prices for the upgrades. You can even lessen the hordes of cats as the waves progress. That way, the player can be less pressured.
This game blows. I really want to give it a 10/10 and 5/5 because of the great graphics, programming, sound and music- but it's just too hard. I feel kind of sad for not giving it a 10/10.
Make this game easier!
