Thanks for playing! I'm glad that the designs all felt unique, I wanted each of them to stand out at least a little in their own way. Honestly I got kinda carried away doing designs - had to stop myself from trying new ones out or I would've run out of time to do the rest of the game!
That's a lot of good points to consider for improvement as well, a little more direction would definitely go a long way to improve playability, and there should definitely be some more snappiness with the navigation.
