Well done on the juice part ! It is very satisfying to hit enemies in this game, especially the snails ! The art style is really cool too, maybe the background could have been darker to make the moving elements stand out a little more, but that is just a matter of preference.
The small attack range combined to the speed of the character make the game really hard ! As it is a scoring game, it's not too bad but making it a bit more forgiving could help the player to master the controls a bit quicker.
I had a bug once, where enemies were invincible, but I couldn't find any crystal. Maybe it was offscreen or under the ui ? I think making an effect like an electrical arc between the crystal and the enemy would prevent that, even if is was offscreen I would know where it is.
Good job, that's a pretty fun game !
