Sure, I could do that too. Now that I'm basically done with school, I'm trying to learn some new skills I could use to put towards creating interactive apps such as games and websites. One project I am working on though is a UE4 action-adventure game with some current and former students at my university. It's kinda 2 projects in one where one is the game itself and the other is a framework plugin for UE4 meant for other devs to use who also want to craft AAA-style games in UE4. I'm one of only three programmers on the project as of now, and as of now, I'm working on refactoring some of the codebase, basically making everything neater, a lot of backend stuff that would not be visible in game. But something I did make were a couple demo puzzles when I was coming on-board the project just to get myself more familiar with UE4 and the framework.
