No SFML libs included with the Linux build, though I got it working. I've made games without an engine before (raylib, instead of SFML). I understand the difficulty and all, especially with the time frame. The movement is a bit jank. I also see in "roomdat" that some levels were meant to be loaded from images... bold move to do in a game jam haha, hard coding it is the only option you have with such limited time :)
