By far one of the more unique games in this jam, and I found it to be super fun!
I've gotta instantly agree with angelkof15 about level 4, it was by far the best demonstration of the concepts for this game and it was super cool to see everything come together as you got past all the guards.
I also agree with the general consensus that there is some need for polishing in terms with loss and level reset, the most common glitch I ran into was pressing space too fast to create an echo after getting caught by a guard only for the guard to just slide across the map to get me, but this was solved by just pressing "F" to reset and then the guard went for the echo as it should, which brings me to my next point that I really appreciate the always available controls menu, this game has a lot of unique features so pressing "C" to see the controls was really nice and helped me a lot during my playthrough.
That being said I think concept-wise this one has gotta be one of my favorites. It was quick but complex in a fun way. I think with some general polishing of the loss and level reset mechanics and a couple more levels similar to level 4 this could be a really fun and unique product!
