So as of writing this, you've got the best submission I've playerd so far. The theming was well thought out, the mechanics were consistent, and the application itself runs as expected. There are a few little touches I really liked, like how you dim the screen to ease the transition between frames and how you found a song with the right BPM so it's almost a rythym game.
The one weakness this game had for me was some of it's telegraphing, specifically things like guard sight lines and who saw me at a given point, but otherwise this is top shelf stuff.
