Hi! No, this isn't an engine, it's a game that comes with its source code. Sadly, there's no documentation for it, I mostly released it as is for people to be able to play it even when I can't support it anymore.
TileD can be downloaded from: https://www.mapeditor.org/ and there even is a version on Itch IIRC.
