Well this is interesting. Prefacing this by saying that I am not a puzzle game enjoyer, I am fine with them as an addition to something but I don't usually play them on their on. As such this was somewhat of a challenge as the floors are a bit difficult for my mush brain to handle.
However after spending a bit and solving the puzzles I would say that once you solve them, their design feels interesting and clever.
I rate the programmer highly, it is awesome.
The background sound though fine could definitely use some work. Overall though the puzzles felt nice and though very difficult for me it was still fun. (I wish the jetpack would carry over lives.)
