Aside from getting the last level first I really enjoyed your game. The echo makes it so you can have your actions repeat without restarting the level. this really helps the pacing and makes mistakes much less punishing, encouraging experimentation. The art also was fitting for the gameplay.  Also the looping does lead to funny moments. for example one time I was trying to get a box into position, and my echo came along and yeeted it across the screen, snatching it out of my hands. minor gripe would be it would be nice to be able to reset the levels and pull the boxes because i got soft locked from a box hitting the wall.  Congrats on submitting! 

Ok so due to the build issues is kinda hard to give propper feedback but gonna do my best:

First of all I've seen quite pleanty of games taking the theme in this direction but this is the first where I feel the echoing is actually the CORE FOCUS of the challenge, well thought out, love the fact that leaving the rift and starting your eco takes brain power.

Main gripe is that with all you have here if there was just a little bit more use of the visual arts in the indications of the game the ramp up (once you get it in order xD) could be way more intuitive and less lead by the nose, allowing the player for some WOHA times.

The gameplay was nice. Would be cool to have a bit more puzzle elements. I like level with overlapping zones. Not sure why game loops itself back to the first level. Also the game lacks of any sounds.

Very cool mechanic and art style :) Really loved it <3 But next time please add tutorial to the game (i mean in game)

I enjoyed it, would like to play it more

Nice puzzles. Laying multiple zones on top of each other led to some surprisingly fun behaviors. Would like to see more of those puzzles.

One thing that would have been nice is a reset to stop the looping. I reloaded the browser once because the ghost was getting in my way of setting up the next ghost.

Nice to see more games being built with bevy in the jam.
