This is a very nice game. It makes me think of Apogee,
Captain Comic (have you played that game? I'd be surprised if you hadn't) and old science fiction movies, which are good things.
I think that the graphics are wonderful, especially the film projector effects, and I like that it is mostly serious and melodramatic but that it sort of mocks sci-fi and video game conventions. it could be a little more subtle about that, though. My other criticism is that it banks a little too heavily on the player's mastery of an honestly slightly frustrating jumping system, and that it is pretty unforgiving at times (making the player trudge through multiple rooms just to get back to the part on which they keep dying; this was mainly a frustration on the room with the lava, the first crab generator and the switch in the bottom left of the screen, if you could possibly know what I mean by that). The fact that I finished it, though, is I guess a sign that it's compelling enough to make up for the frustration.
I got a small bug, also. Sometimes when I would jump and just barely land on the edge of a moving platform, he would get stuck in "jump mode". This did not kill the experience or anything, but you may want to fix it if possible. Also, is the ending screen supposed to just stay there forever? I think something should happen to let the player know that the game is truly over and done with and they don't need to stick around waiting.
But don't think all this criticism means I didn't like it, because I liked it very much. But raving about that is less helpful to the creator, I find.
Oh, I also should mention that I loved the sound, especially the music in the opening and ending sequences. That killed me. It sounds very much like a PC speaker, and I like that.
