Great concept, solid execution. I would probably lose the double jump altogether and let the character jump slightly higher, since none of the puzzles would be affected by that change. The game has a pretty happy ending considering the blood-scrawled warnings at the beginning. They seem to suggest there's something sinister about killing your clones, but nothing bad seems to happen because of it. I might eschew the blood and guts, or have a darker payoff in the sequel.
