Ooh, this is a really cool spin on the idea! When the theme was announced, we were also contemplating to interpret the theme as "built something using musical scales", but didn't exactly figure out a good game mechanic with that idea, glad someone else figured something out. I love how a track slowly evolves over time and it's nice that the levels allow for a bit of artistic freedom. Character movement seems a little weird and towards the end of the second level I broke it by accidentally recording a note on my previous playthrough that I think messed up any chances of escaping. Would be neat if the characters also moved on time, but I can see that becoming tricky with the climbing mechanics. Overall, I love the concept and would love if you continued working on this after the jam, I think there's a lot of potential still in here. Great job!

Super unique idea. It's very polished for 4 days and the level design does a good job of toeing the line between a puzzle game and a rhythm game. It took me a second to figure out what I was meant to do (even tho it was mentioned before the game started). Maybe some in-game text to lead the player in the first tutorial level would be helpful. I'm nitpicking criticism tho this was a super unique and clean game.

This was super unique! Pretty tough to grasp, at least when you’re tone deaf like me. But I liked it nonetheless. Props for the themeing too.

This game is the most unique interpretation of the theme I've seen this whole jam. The music and mechanics word perfectly with each other, the story is simple but beautiful.. and so addictive,  I completed every level and I am thirsting for more, its truly impressive work!

One of the most unique games I have played in this jam. The fact that the level both works and sounds good is amazing props to you.

First thing's first- I can't believe a single person made this in 4 days. Hats off to you! I love these sorts of games where I'm the guardian of predictable AI entities and I have to control them through indirect means. Playing with a level editor that makes pretty sounds is both unique and rewarding, and hearing my compositions layer on top of each other as I ascended was a fantastic feeling and a perfect example of what makes the interactive medium so uniquely powerful. My only constructive feedback is that the layout of keys felt unintuitive on some layers of the tower and broke the illusion that I was playing piano keys. One example that comes to mind was when the 'A' key served as the note one step above the 'M' key. It was an extra layer of mental gymnastics that made certain floors trickier than they needed to be. Because the game never requires use of more than one octave at a time, I think the keys used could have been consistent across all floors in an unbroken left-to-right layout, similar to a piano. But don't get it twisted- this game rocks and my singular gripe didn't hamper my enjoyment. Outstanding work, and you can bet I'll be checking out your future projects!

Wow, this is such a great concept! What a cool take on the theme. I don't know how to make music, but it was really cool to feel like I was being guided into learning a little bit haha! It was a really fun experience, excellent job!

Here's some feedback if you continue to work on this game post-jam (I think it's a really cool idea, not sure if I've seen something like this before!):

• I was definitely confused how the game worked at first, once I started to get it though it felt good!
• Sometimes it seems like if I hit the record button mid-playback or mid-recording some of the notes would continue playing. It doesn't really feel good on the ears when that happens.
• I didn't get to the very end, it seemed like the very last part had some weird collision or something? The level right before that which required a lot of different key combinations felt very satisfying and rewarding to me though, so I felt OK with stopping after that one. 
• There was one time where O and E fell down to another part of the level, I thought I may have soft-locked, but I realized I can get out of it by hitting record again.
• The movement of the characters felt weird, and there were a couple parts that felt confusing. For example, when I got to one of the staircase parts I was like "how are they supposed to get up?" and then I once I saw how they move I was like "oh they can get through diagonal blocks." 
• I think my keyboard layout was OK with this, but it might be good to add support for different layouts. Unfortunately, you can't really do mouse alone from what I can tell because of chords. Or maybe just a handful of keys at any given time so you'd only have to bind a handful?

Overall great job! This was a fun experience. I think it's a really cool idea that can you can expand on. Thanks for making this!

Was a bit hard for me to learn, but once I got it, I could not stop

Loved the game! A really cool concept, well executed. The take on the theme is nice, too.
