Holy cow is the vacuum sound loud! ^-^
Jokes aside, the game is really solid and fun! The concept is simple yet appealing and so is the artwork. The puzzles are really interesting and I love how some of them even allow multiple solutions: maybe you could implement a rating system that gives the player a discrete score depending (for ex., 1 to 3 stars) on how much blocks they placed and how much moves they needed to reach the solution.
Really a great job, would absolutely like to see more! :)
