The concept is very unique and I enjoyed it quite a bit! I did have some trouble understanding the game's controls when I first started. I didn't realize for a while that the center button was to start the level since it had a pause icon on it. I also assumed the crumb needed to be as close to the large crumb as possible and was confused when the rat didn't react to it. Between those two issues, I thought the web build was broken at first since nothing happened when pressing the center button. I did eventually get it though! Maybe having the center icon be a play button at first and showing the range of effect for the crumbs when placing them would help. Regardless, it was still very fun!
