aaa finally at last i found a thing so it goes like this (i cant remember the name so i need help, thanks)

It was a browser game, possibly a website from what i remember (?) where you could enter levels, place down these ''things'' that defend in spots from the bad ..things coming out a tunnel on the first few levels, the bad things went on a path trying not to be shot or slowed down to grab a certain coloured (or color depending where you are from dfsjnj) generic diamond shaped gem then walk to the end, if they did that you would loose a gem but if they got killed, you got it back. The layout was kinda like a forest in the first few levels with areas to place the ''things'' that would help you kill the bad things.. I think you could upgrade the good ''things'' to shoot faster and reload as such?? The only actual good ''things'' i can remember was a slow volcano that shot cannonballs? and maybe one that had water to slow down bad ''things''

I forgot how old it was.

If you could help find the game that would be kinda helpful thanks

(and hopefully it didnt get erased at one point in time)
