Martze’s “Soul Searching” plays with a lot of cool ideas I haven’t seen explored in a VVVVVV level before. This one’s a little trickier than the other levels I’ve featured, but worth persevering with! It’s fun, polished, and extremely inventive.
To play a VVVVVV player level, extract the .vvvvvv file into your VVVVVV levels folder. On windows, that should be in My Documents/VVVVVV, on Mac it’s Documents/VVVVVV, on Linux it’s ~/.vvvvvv
