To do different attacks, remember that there's more than one attack, you have to try different combinations of the up, down, left, and right arrows. Also, when you attack down on the ground is different from attacking in the air.

To go back to the menu during gameplay: Hold down backspace and don't let go while the game is paused for 3 seconds.
To go go through platforms like the real Super Smash, just hold the "down" key for half a second and you'll fall through.
To change the match from Stock (Using Lives) to time (Timed match) and other options: In VS Mode you can click the text at the top that defaults to "3-man survival contest!" and there you can change the options. Timed matches are different from stock matches since you get unlimited lives and whoever gets the most points wins. You gain a point for KOing someone (knocking them off the stage) and you lose a point for getting KO'd yourself. You can also play Stock and Time matches at the same time but the winner will be based on the amount of lives everyone has left. Also, to change teams you can click on the word "Melee" on the top left.
