The music is so soothing, and accompanies the gameplay so well! The game feels super relaxing to play and is easy to pick up. Nice touch on making the bridge selection screen see through when moving your cursor away (I was actually going to complain about it blocking the view, but then read the description and saw that the issue was already considered). It would be nice to show the player what the end goal is before having to just start placing bridges. I think something else that could be done is when it's impossible to bridge to the end, a game over screen could pop up, or just restart automatically. Nice job with your entry!
