FINALLY! After years I have found it! I used to play this game a lot back in elementary/primary school. Although, it would not be on Newgrounds but on a different website. On other websites, it is not laggy, but for some reason it is here. Oh well. I was never able to beat this game because one of the levels just seem impossible. I guess other people feel the same.
And I see some people say that level 10 isn't possible, it is.
Edit: YES! I finished the game! It was easier than I remember tbh, but it also put up some challenges. And the quality increased so much in the last level holy shit-
