How to download MonoDevelop and use it in Unity 2018?

Unfortunately Unity has stopped supporting Monodevelop-Unity on 2018.1.0 release. However you can still use Monodevelop-Unity by downloading the Unity Installer of version 2017.4.7 from this link: https://unity3d.com/get-unity/download/archive , choosing custom install and selecting to install only Monodevelop. After it’s installed in your PC, you can select it as the script editor in any version of Unity.

Designing Action Game

Unity: What to consider when designing an action game

First of all, what would classify as an action game? If I was going to give a simple answer I’d say that it’s simply a game that has a high amount of decisions per second and you can increase the intensity of the action by either increasing the frequency of actions per second and/or increasing the complexity of those actions. I personally believe that this is where the mobile market is lacking.
