Thank you so much for the feedback! I really appreaciate it! I will be working on the difficulty system that is very simple right now and you're totally right, a couple of warm up rounds are necessary. Also, yes. I will be adding more boards and a in-game currency system based of the points you achieve in each game to unlock the new hoverboards. I'm currently modeling new designs so it make take a little while but more hoverboards will definetely be added!
