I just finished playing this game's eight levels, and I loved each and every one of them. When I entered the first level, the fundamental mechanics were a little confusing at first, but since I was able to quickly restart the level, I was able to get a good understanding of them before I entered the next level. The artstyle is so eye catching, especially with the designs of the machines, and I love how the music is loud and bombastic. It really fits with the factory idea, and helped me stay motivated when I was stuck. To top it all of, this game 100% nails puzzle difficulty and difficulty progression, especially with the final level. I won't spoil what it is, but I did have to take a few minutes to just look at my screen, assess what I was given, and figure out what to do with them. However, I wasn't annoyed by this. In fact, I was anything but annoyed. This final level didn't feel substantially harder than the last levels, and gave me enough freedom to really put what I learned from the past puzzles to the test, which I really appreciate! I felt so smart mapping out my solution and figuring out how to deal with any of the roadblocks, and when I finally beat the level, I was so proud of and satisfied with my performance. Overall, this is an excellent game that reels you in with its superb art and sound design, and keeps you engaged with its well-crafted puzzles, which will make you feel proud of your problem-solving skills, even if you didn't discover the solutions on your first try!
