Great level! I ran into some problems in the green tint version.
x1006y1001 drops you into a void instead of warping you over a screen, but I suggest you forget the warp and move the screens below because screen x1006y1004 is a duplicate of x1005y1004. The duplication makes it impassible. Screen x1000y1006 has music playing over the looping music. There are voids when jumping to either side of x1007y1003, and the updrafts in x1000y1004 through x1002y1004 can send you to the voids above.
@ortoslon: When you touch the keys the doors open automatically. You don't actually collect them.
