Nice concept so far
I've tried plenty of fitness vr apps including weird ones that are in the depths of steam, and this one stands out. This is like a fluid boxing movement that really engages your core with twisting and punching. Even without a full game, the gameplay alone has me intrigued enough and feels natural enough to keep playing and moving. I find myself pushing to get all the rings and once I achieve that just slightly bumping up the difficulty with one of the sliders. At the lower levels, it's great as a warm up, but then pushes you to the limits of how fast you can react with the harder difficulties. I'm impressed, will have to try the coop soon with friends, and listen to music while I play.
