Tall.io
The IO community is constantly growing, and it's getting harder to develop original ideas about making a bigger number. This game manages to do it by making it about people who want to get bigger by getting taller. It's about focusing on yourself without losing sight of your opponents, who may be moving as fast as you. Then there's the luck aspects of the power barriers that can completely change the tides for whoever is fast enough to reach them first. There's no time to rest, so you'd better get moving, gathering, powering, fighting, and start growing up to win.
