Stuning, the visuals, sound effect, clean gameplay concept and this is well polished also! Magnificient job
The only thing is, you can ‘cheat’, which takes away some of the ‘flavour’ in my opinion. I don't know if it's wanted or not, but you don't need to stop time to move pieces, so by fiddling with the pieces while the others are in motion, you end up adjusting everything because it's a closed cycle. Anyway it could also be a way for someone who is stuck to make progress as well.
