This was cool, good job! I like the idea of pickup enemies and tossing them around, that's a fun idea. The door transition is cool too, I've been doing basically the same thing in all my games, just with different sprites lol.
Including the controls in the description of the game would probably help a bit. Also, I might have just missed a mechanic, but I couldn't progress after the second enemy. It looks like there's more to the level, but I couldn't figure out how to get up that ledge. Again, I could have been missing something.
Overall, great job!
