Whyyyy is this so addictive? I struggled, really struggled at first. The key to success: the power-up that shows the predicted bounces. After that I got to #4 on the leaderboard! Woo. I probably could have gotten higher, but misclicked a piece and put it in an impossible spot (needed one of the floating balls to get to it). Simple aesthetic and awesome gameplay loop. I can definitely see something like this blowing up on mobile.
Two notes: First, the music. I played for awhile, so maybe it just became exhausting to me, but the loop was too short and too repetitive. Definitely the right style of music, nailed that, but maybe a more fleshed out version? I don't know. Second, the challenge. I don't know if there is a way to curb the difficulty as you progress, but it felt higher stakes at the beginning. Maybe it's an asteroid (bad example) that comes in every couple levels that takes out a chunk of the map requiring you to rebuild the easy paths you have built yourself. Or a strong wind (another bad example) that rotates pieces to face a different way. Just a random thought. Feel free to ignore it!
Either way, great entry to the game jam and great game!
