Inspired on 8bit and 16bit era games, Easy Menu System is an asset that lets you easily design menu prompts for your game. It's just two objects (one for menu parents, another one for menu control) and three scripts. Easy Menu System is designed with usability and hackability in mind, so you can use it on any circumstance (as long as your game controls with keyboard or a gamepad!*)
Comes with an example project so you get some ideas on how to use it!
*gamepad not supported, although it's easy to write the hookups for it.
