Alright, the mechanics are great, I love the grid style based puzzles , great concept. The visuals are okay, nothing special BUT the audio could use some work. The physics are nice and it feels good to play after you understand the objective. This game would be 100x better if it had any type of practical tutorial / text in the background for the first couple levels to teach the base mechanics one at a time. Otherwise, a pretty good game, even more impressive if it was made in 1 day! Great job, keep it up!
