Great music to go with the game, the mechanic works well especially with the spiky walls, I love that you can stop them. some of the later levels did get a little tedious when waiting for the rewind to happen.
Thank you for your feedback! I agree that it may be tedious, especially the later levels . and to make gameplay a bit easier in the future, I do plan to add a few more levels. Therefore, I am planning on adding a function to remove the last box, as this will make gameplay a bit easier.
