The first Hard-Fast-Air enemies level (315) on Medium difficult.
Edit: Due to some nerd calling me cheater, before calling me cheater please tell me whats the point about cheating on this game, and some proof please. By the way be careful, you may get pwned.
A "Rush" Battle (10secs between NEW's) on NORMAL difficult on the flash game "Strategy Defense 3", which is similar to the tower defense games.
PD: Since I didn't turn the particles and the quality to low, at the end theres a lot of stuff and it lags some. And sorry for the no-music, for some reason I'm not able to record it right now.
This is of one of the first versions of the old Flash element TD game, when if u spammed the "next level" key between levels, u could go lot levels further and some strange stuff.
