The FSEngine is a light-weight 2D game engine build on LWJGL 3 and contains a super-fast rendering system, a fully working gui system and a map parser. Best of all the engine is 100% open-source with much more to be added to it and is programmed solely by me. It’s up on github here, for for your use: https://github.com/LordC777/FSEngine
I have a lot more intended for the engine with version 1.1, you know the whole day 1 fix thingy, yes this is the week 1 fix.
