I didn't understand why some connections are brown, but it doesn't seem to break gameplay fun:) Nice sounds! 

Good puzzle game! I think you did a good job at making the levels progress in difficulty at a good rate. Level 5 started really making me think!

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! :)

Great one! last 3 rooms super entertaining. How the numbers operated and what was i trying to do, I didnt have to think very hard until those.

Also the art is super clean and the sounds fit a lot.

Nice puzzles, but I didn't really understand what I was doing until last 2 rooms.
