Thank you. I'm so glad you enjoyed playing the game <3.
Unfortunately, I do not think I am going to make any more. It turns out what I thought was a simple concept of flipping and replacing all the assets for mirror levels was really hard to implement, because there was no way to just mirror each piece based on it's position (the xy position appears to be set at the corner as opposed to the center, so I couldn't just put Mirror Block A the same distance from the right of the screen as the non mirror one was from the left). After I submitted the game, it occurred to me I could have taken a screenshot of each level, flipped it in an image editor, put it in the mirrored level and put each piece on over the image, but I don't know if I got the patience for that at this point.
