It's a nice puzzle game! Simple and intuitive, I could easily jump into the game :) I like the sound effects, really sounds like it's powering up.
A point for improvement maybe would be a sign that you finished the level aside from the sound effect. I played with sound, but someone playing without sound wouldn't be able to tell if they got it right until it's already at the next level.
I hope you make more levels for these! :)
