The same as normal GD. Completely possible (verified). However, you might find it a little harder than the original:) ADVERTISING ENCOURAGED:] I'm not done yet. I finished stereo madness, back on track isn't complete, and I haven't even started polargeist. But you can expect what the 2nd and 3rd levels will be like from the first. Also, if you have any ideas, comment below.
Credits to griffpatch. All I did was use the level editor in some... interesting ways:)
