Great job on this project!
The visual presentation immediately caught my attention. The effects, atmosphere, and overall polish give the game a very distinct identity. I also thought the echo mechanic was a really creative interpretation of the jam theme.
The puzzle design feels clever and the whole concept stands out from many of the other entries I played. You can tell a lot of care went into both the mechanics and the presentation.
The overall experience feels polished, unique, and memorable.
Congratulations on the submission!
