It’s a great little game, for what it is. It could have been a lot better with just a little extra effort on the non-puzzle game elements.
You have to move blocks, and over time, you learn various systems to get the blocks where you want them to be. The music is monotonous and there aren’t many satisfaction points- no cool sound when you pass a level, or even an ending animation for the level beyond the slightly flashing dock outlines. It just instantly moves you into the next challenge, which feels unrewarding.
The end has this problem, too. There’s no “chapters” for the different kinds of challenges, you just move through them all in linear fashion, until you’re suddenly back at level one. No ending, no warning, just “oh look, one square on the screen.” Worse still- it forgets any progress after level 88, so you’re perpetually stuck on the last level whenever you open the game after solving it once!
So, the puzzles are challenging and interesting, but the rest of the game design is definitely lacking. I still recommend it, I just want you to also know what to expect so you aren’t disappointed. I’m giving it two stars for the puzzles. I originally gave it four, but then discovered the “stay on the last level forever “ bug.
