This is a fantastic entry, well done team! ^-^
Things I loved:
- Really inspired use of the limitation!
- Having 2 dimensions for the player to come at the puzzle is really crunchy and satisfying
- The artwork, fonts, theme etc are all very polished, it felt like I was playing a released product!
- Big props on the transition screen, I love that effect
- Difficulty curve was very balanced - felt both challenging and a logical progression
Things I'd love to see:
- Maybe a phone app "star rating" style scoring system would work well here - like a par number of swaps, or having a Submit button that lets you check if you got it right and you lose a star if you missed something, etc
- The length was perfect but I'd still love to see more levels! :D
