Wow, I must say, I personally adore this game! It feels like a breath of fresh air to me. Everything about it showcases a sense of uniqueness and specialness. The music used is delightful and perfectly complements the game, while the art style, with its distinct pixel art, stands out beautifully from many other pixel games i've seen (both in this and outside the jam).
One aspect that I truly love is the mechanics. I find it incredibly enjoyable how the game gradually guides your hand in the beginning and then allows you to connect the dots based on what it has taught you. For instance, the idea of only your younger self being able to traverse thin bridges but unable to jump, necessitating a switch between the two characters, is brilliantly executed and adds a solid layer of enjoyment in figuring out the puzzles.
Moreover, the writing in the game is splendid! Personally, I enjoy it a lot. However, I do have a suggestion to enhance its presentation. Perhaps incorporating it into a storybook format or even having it whispered in your head by a shadowy figure that follows you could add an extra layer of immersion. This idea just came to mind, so take it with a grain of salt, but it could potentially elevate the overall experience.
I did encounter a minor quirk where I unintentionally triggered a jumping dance party by hitting blocks underneath and holding the jump button. Aside from that, the game is remarkably free of bugs, which is a pleasant surprise. (for a 3 day jam just amazing how bug free it is! I can't express it enough haha)
If you have plans to expand this game (which I highly encourage, as it possesses a lot of potential), I would recommend introducing more complex puzzles and implementing a pause menu. Additionally, adding some flair to the main menu, which currently feels a bit unfinished, would further enhance the overall presentation.
Overall, despite a few minor nitpicks here and there, this game is an amazing little puzzle platformer! I genuinely hope it evolves into a larger project because the potential it holds is truly remarkable. Keep up the fantastic work!
