Hey there! Just played your game and I must say this is amazing :D. The puzzle design is so good and I still don't understand how the actual mechanic works😅, kinda just trial and errored my way through the levels but it is super cool. The art is also really simplistic and nice and I think it fits the tone of the game, and I do appreciate the tutorial and the gizmos on the top left. I don't have any real critique for this game because this is prob the game I've spent the longest for this game jam because it was super fun to play. The only thing I'd probably say is you should maybe prompt the user to undo their action when they die or automatically respawn them because I restarted the game when I died the first time😅
Other than that, it's a great game jam entry so good job :D
