As always, you guys come with absolute bangers, with tonnes of polish and great attention of detail, great stuff.
I'll try to not repeat what others have said and mention other things:
I liked the level design. To the point that at certain moments I loudly exclaimed "oh you bastards" because I was always 1 block off from a "clean" solution. Of course it wasn't actually frustrating at any points, it forced me to think differently and in the end the result was very satisfying.
Another neat bit of detail were the "cutscenes" between levels, where it was obvious it's the same person, just two sides (literally). I also like the way audio amplifies the pieces of dialogue.
I usually feel like I should include at least some downsides to a review, but this time around I feel like I would be way too nit-picky and I don't wanna be mean. All I can say is, I want more, keep em coming!
