Hi Iván Ávila,
Thanks for all your CPC games. This one is really fun.
Is it possible to finish it as I can't get past level 4- wave 6?
If you have the strategy to get rid of it, I'd be very curious to know it.
I've just spent hours trying to figure it out, but it's beyond me.
I made a little cover for the game you can see here :
