I really like the presentation, everything feels polished and there are lots of satisfying visual effects and sounds for every interaction! The music fits the action really well, it's really good at setting the right kind of hectic pace to the action. The art is great and has a well defined and consistent theme.
The pace of the gameplay feels a bit on the fast side, it's not always easy to get a sense of orientation in a new level before the clock starts running out. The check for connections does not happen immediately which sometimes leads to overclicking since the game strongly encourages players to hurry.
Overall the gameplay is very fun and offers some interesting twists on the dropping block puzzle genre. Great concept and excellent execution!
