I've worked on MeltDown and TowerStorm games from DimensionU as a sub-contractor of MuchDifferent and ported them from uLink to uNet networking. Games were real-time multiplayer and I also found a bug and its fix in uNet's WebGL implementation in the process.
The projects were built with Unity 5 and I've only done the port and some adjustments which were needed to make them work on WebGL. Porting from uLink to uNet was relatively good considering the fact that at 2016 uNet (specially on WebGL) wasn't yet that much tested and stable. Unity's engineers were very helpful in the process and working with the project owners was very nice and easy.
