Nice...
For a first flash game, it's not bad at all... could have been more to granted... but not the worst thing I have ever seen around here.

Nice!
With or without sound, it was excellent for your first try! Congrats, and try to make more.

This reminds me of starcraft. Where did u got the enemy's and lizard from?
The game could use sounds but if it didn't work out that's ok. It's cool for a first attempt.
good game
good game, only suggestions i have are to make it progess smoother. if gets pretty hard pretty fast. maybe a few power ups and a bomb or somthing? just some thoughts! fun though, keep at it.
standard defense game but..
this was actually fun as a suggestion i think you should improve the graphics, make different enemys with different attacks and change the background for each level
