The simplistic look of the game is really interesting! I cannot help but imagine the protagonist is running through some giant machine, whose purpose nobody really knows. Maybe it's cloning them?
Also love the giant monster merging into the facility.

The soundtrack really elevates this game too: It's a nice mixture of relaxed moods and made me nod my head while playing. Of course, it also really helps with getting over a few difficult bits. 

Only thing missing for me personally is a bit more variation within the main character's move set, but I would assume the simplicity was very much intentional here.
