Aww I love this! It's all cute and fluffy and pink <3
Everything fits well together and is pleasing to look at, the sounds are also adorable and the music fits well. The clouds are environmental, and the gameplay really incorporates the fusion theme in a creative way.
There's really nothing to complain about, except at a certain point I couldn't progress and I didn't know whether I was just too dumb to figure it out or whether it's because the game isn't finished (as you mentioned in the description).
In any case, I'd say this is a personal favorite of mine so far! :D
