need a small suggestion
i am a beginner in android development and i have developed some basic apps and now i have been given a project in which i have to make the game exactly like "Color Switch" game most of you have played this game, its famous with 100 million downloads.
So my doubt is that , since this is a 2-D game, do i have to use game engine or not, if game engine must be used which one is preferable, Unity or LIBGDX? i am confused to choose and also i would be thankful if you give me link to some tutorials.
