I was required to develop a clone prototype of the popular game Clash Royale as a practice project in my internship.
It has to support Clash Royale's basic gameplay features such as energy system, unit mechanics, and card system. The player has to be able to play against a simple AI that randomly deploy units after units against the them.
I wrote the gameplay in C# and also created assets used in the game. It took about 3 days from initial planning to the completion of all the required gameplay features.
