it's, ehhhhh....
Look I love tower defense games..
and i know it can be hard to bring originality to one, but around lvl eh, 23.. I realized my truly impenetrable fortress could nary be improved on.. and that's when the lag happened.. It just, crawled. and it didn't matter, my doom walls couldn't be defeated either way. I guess I'm just asking for more than JUUUUST TAAAAANKS..... even if this is newgrounds..
