Wow that amount of time you might have done it is very fast. I really liked the clean mechanic and the interesting idea.
One thing is when I get to the second level, no matter how long I wait, no aliens ever appear. Nothing else to grapple ever appears, and clicking the right mouse button anywhere doesn't do anything.
For the rating, I don't consider this part, just in case it's only an issue for me. I might try it again at some point as well.

For the second level you need to to roll over the gaps to reach the area with the aliens, I assumed players would just figure out that this is a mechanic but tbh that's bad level design on my part. If there are really no aliens in the level though then I don't know what the bug could be, thank you for playing though!
