PLEASE add the ability to restart the level by hitting R. It makes it much easier to do and would be easy to implement. All games should that involve levels that may need to be played again should have this, just as all games should allow both keyboard and mouse options to go to the next level.

i dont like it! i LOVE it!

Not a bad game, puzzles are easy enough. Maybe a little too easy, and very similar to an app I have on my phone. All in all, not a bad game

Love the gameplay mechanics, and its very addictive. The puzzles are difficult without being frustrating, and the music is relaxing. Nice Job!
