Made it to the end! The level where you have to stay in the first countdown block to not get trapped was my favorite, just the perfect timing when you get stuck in the little area for the first time and the realization what just happened sets in, lmao.
Super fun take on the theme! I loved the puzzle designs and how they teach the mechanics organically. Like in the platforms-disappearing counter level you see it and you immediately get what the puzzle is about (but not necessarily the puzzle solution). I thought that was very well-designed, super clean. Also want to point out that it was cool how many different mechanics made it into the game, like every level had something new in it, that was awesome and kept every level fresh and unique.
Art and sound design as well, super good-looking pixel art, again, just clean. Same with the sound effects and the music, especially the music is really perfect for hitting that "figure it out" platformer puzzle mood, great job on that as well! All around very well done, super cool game!
