wtf how do i play without downloading because i just wanna test it out

Runescape?

You dont download runescape, you play it in your internet browser...

Just go on www.runescape.com and press "click here to play"

Runecrypt is a fansite for Runescape, and in no way a private server.
Private servers are against Runescape rules, and I would recommend not using them.

Although, you can use our client "Fallen X" to play Runescape, which has an option to be used from the browser, without downloads, and you get access to hiscores and many more awesome features. You can access it at: http://www.runecrypt.com/index.php?pid=998

Thanks
