Very cool game. In my first play through, I initially didn't even know I was supposed to be getting a multiplier or what the purpose of the butterflies were. I assumed they extended my time in the level or something. After I understood, I gave up on level 4 after several tries, but I just felt frustrated that I wasn't able to find the windows fast enough. It wasn't until coming here and reading the comments did I realize how important headphones/earbuds are for this game. They are required to pass the later levels. After that, I came back and cleared each level in my first try and got a score of about 10,000. I think a lot of players are probably running into the audio thing and don't how much that helps. I really loved the art of the game, some of the best I have seen in this jam so far. And the audio was stellar as well, even before I realized how crucial it was to the game. I do think the levels could be a bit shorter. I think people will be frustrated at the time commitment and loss of said time upon losing a level and having to restart. I think these kind of games really shine when the player's toolkit expands with the difficulty of the game. As in, new things to use; abilities, movements, etc. Things to help against the rising difficulty, because then the difficulty can also come from having to spread themselves over a wider variety of tools and think about how to use them, but also use them over a more difficult set of challenges. I know that can be hard to pull off in a jam, but maybe for future development of this game. Overall, I think this was an excellent entry and y'all should be very proud of this one. Well done :)
