Wow! Fantastic and very clean entry, loved the different puzzles, the style and the coherence of the game's theme. Here's a bit of feedback: There's a little visual bug that happens when using tilemaps in unity, this might get fixed by disabling anti-aliasing. However, it's only visible in the black parts so it's not that important and doesn't interfere with gameplay. Design-wise, I found the level design excellent, the only part that bothered me a bit was that one of the middle levels was noticeably harder than the ones after it, making me think that it was the end level and therefore confusing me a bit. Nevertheless, except for that level, the difficulty curve and the addition of new elements for the puzzles was really well put together. Finally, I lacked a more developed use of the GameJam's theme, since it didn't feel like it had much impact on the design, meaning that I though the game could fit in so many other themes before this one. Anyways, great game guys! Very good job with having a polished submission in such a short time limit.
