Answering to AlexVeebee, the levels are generated through a Python script, not "AI". I did check the script and there was a bug where the color could have symmetrical endpoints in two levels, meaning it starts in [0,0] and ends in [0,3], while in the other starts in [0,3] and ends in [0,0]. It's practically the same level, but it's recognized as different by the script. I will change the levels that you said and check for any other identical ones, but they will stay as completed for those that did them. I'm sorry, I went through all the 5x5 levels and honestly didn't notice. As about the music, I launched the update called Jukebox that fixes everything they said.

Here's to my first ever game jam!

Since I can't answer to reviews, for the person that didn't understand the rules: they are taken word for word from https://www.puzzle-skyscrapers.com/. If you have a row with (4, 1, 2, 3) or (4, any other numbers), if you were to look at it from the left, you would only see one building, the skyscraper of height 4 blocking the other skyscrapers. Basically, it represents how many numbers are bigger than the ones before. In a sequence (1, 3, 2, 4), looking from the left, you would see 3 skyscrapers, because 2 is blocked by 3, being behind it, and you only see 1, 3 and 4. You can find a completed level and explanations in the rules section.
