Thank you for your comment, we're glad you appreciated our game. I'm also pretty competitive, my highscore at the moment is 3830 .
We definitely wanted to add a leaderboard, it was on out backlog of things to do. But we were both pretty busy on the jam period, so we focused on the mandatory features and gradually improved according it was possible to our schedules, unfortunately a leaderboard would take much more time than we had.
