A 3D MMA fighting game currently being developed using Construct 2. Coming Soon to Android and Windows.
maybe you could also make the time of the rounds customizable as well.
Thank you for your recommendations. I'm developing this alone and I'm trying to stay away from multiplayer so I can eventually release it. There's also going to be a Fighter Creation Mode so you can customize the fighters however you like. I like that idea of starting the career with a low rating. Same goes for the store to buy items. A lot of your suggestions are already in my plans. This game is much larger than I thought it would be and it will take some time. I'll try to release an update soon.
