Twinis! This is the kind of twist on crosswords that I love! With mirrored seed entries!
This was the right level of difficulty for me. The vowel hint ended up helping but in the wrong way - I had ANDES in the left grid for 1D, and then was able to put IDEAS on the right and finish that half, before swapping back to the left and correcting my mistake.
That made me think of two options/alternatives instead of disambiguating the two grids via instructions:
- Make the 5x11 (or n×(2n+1) ...) a Schrodinger, and accept either arrangement
- Make it a 5x5 with two distinct solutions, and let the solvers pick one (this does mean you only solve half the puzzle though, kinda)
Either way, great job!
