Im uploading it on Megaupload right now, I'll post the link when its done. This program runs in JAVA, and taxes the limit to what it can run. Thus, it sometimes jams. When this happens, try resetting the java console and clearing the data. Also, have your RAM limit set high (above 500MB), it helps somewhat. To do this, go to system in control panel, click advanced, then "settings" under performance, then the advanced tab, then click on "reset virtual memory limit", and set the minimum over 500MB.
To my knowledge, this will work on a mac, so all you iPeople can rejoice.
Apparently, its pretty easy to make a level. Anyone who gives this a try, post them, I'd like some new ones.
And no, there is no good way to slide rails, sorry.
