This was one of the most valuable projects I've ever done. Basically, because of this project I really got interested in electronics and learned all the basics about micro-controllers and other cool stuff.
A while ago I was experimenting with LibGDX, I was building a platformer game, mainly to learn OOP and game development
I was working on a game called "Super Droid" a replica of good old game "super mario". I'm using libgdx as my game framework, so it means that the will be able to run on Android with GL2 support and any other OS which supports java - linux, macOS, windows.
