Awesome concept and very fun! Great visuals though I think it'd do with better audio, a calmer more soothing song would have been nice. The game even taught me some words that I didn't know!
Has a few issues, as others have pointed out it would be amazing if the pieces fell after you made a word. The other thing is that when rotating sometimes the letters shifted position instead of staying where they were supposed to!
Overall, great game and I hope you continue to develop this as it's absolutely something I'd love to give another go.
