Adore the presentation on this! The vibe is impeccable, graphics strong and cohesive as a whole, great music and sound effects the whole lot! I also appreciate the continuous narrative while progressing through the game. Sadly the moment it reaches windowed mode it crashes for me, so I could only play up to there. I tried it a few times up till there, but while the window opens and I hear some sound, nothing else happens and it crashes to desktop. No worries, could be my not so up-to-date laptop.
The following is a list of notes I wrote down while playing, but please view these in the context of really liking the game (The more you like it, the more small things become noticeable in my experience!) If you're not interested in player feedback at all then feel free to ignore (we all know we'd want to polish a hundred things but can't within the time-frame).
While I like the animated and timed textboxes (great pop-in animations too), I would personally prefer to be able to move onto the next textbox with a keypress myself. Sometimes they were too fast and I couldn't read what they said. My eyes would first have to find where the new box is and wouldn't always make it to the end, or other things were happening on screen. While replaying after the crash, I would've liked to be able to skip through the textboxes instead.
While most controls are labelled quite clearly I was a little lost at the start of the game, when asked to move the control sticks. My bad though, should've read the text yo posted here! Similarly when asked to hit start or f11, I pressed start on my keyboard, before realizing that was a controller-only option.
The first time the game console starts and you're welcomed to the opening screen, there's an exit placed below the main TV, but it remained non-functional. Because I walked over it and expected something to happen, my brain registered this as just visual extras, meaning I didn't recognize the first exist as being such.
I enjoyed the volume up/down mechanic, but up until the last puzzle that forces you to use it I felt very little need to do it, the optimal route felt like putting volume on full and just running it. Moving my character on the sound waves also felt a little off and unpredictable, the speed wasn't always what it was moving on ground and moving left/right had different speeds, meaning I had trouble timing the soundwave walks.
On the first red/white split puzzle I got stuck by moving both characters to one of the exits, but there was no way back or way to restart the level and I had to re-start the game. I also found these puzzles (especially the one after) to be good in theory, but difficult to execute due to the movement of the character. The slow acceleration start and de-acceleration after letting go of a key made it tricky to do the precise movements the game was asking of me, when movement felt slightly like being on ice.
All in all great presentation, hope you polish this up post-jam as it seems so close to being complete and fully polished, very impressive! Love the glitchy shaders that change over time, too, rather than being the same effect repeated.
