Tsunagari is a tiled game engine inspired by the cult classic game Yume Nikki. It is intended as an open source replacement for the popular proprietary RPGMaker game development suite that the original and most fangames were/are written on. The main focus is compatibility with all features of Yume Nikki, and beyond that it strives to add networking and additional features, and become an all-purpose game authoring suite. Tsunagari is written in C++, using the Gosu framework.
