Good Smash Bros. Alternatives for PC

One question, does Flash 2 lags to you? It does to me a lot of times, when there is "intensive" moments or stages with a lot of pictures movement. It already runs at 30 fps, but this is ok, it also lags to 20fps or even less a lot of times.

I also tried the Crusade now and lol, it runs at 60 fps very smooth, more characters, here is different to make Final Smashes, I don't know if its worse or better, but one negative is that to lower/get off some platform you need to press down very hard 2 times at least which is bad, I like the pixel art graphics more from Flash 2, but a good game that runs at 60 smooth fps and doesn't runs on Adobe Flash like Crusade vs Flash 2 which is good too but locked to 30 fps and also lags but has a way more things to do, I find Crusade better in the terms of just fights, it runs smoothly, lag in Flash 2 makes it hard to play.
