Hm, what graphics card do you use? There seems to be some incompatibility with a shader on your system. I wish I had the time to test the game on other PCs, as I only have access to nvidia chips right now. Well, I tried it on an older i3 notebook with an Intel gpu and I think I got some similar error, but ignored it, as I could not support gpus not capable of OpenGL 4.5 shaders.
I hope I can fix this after the jam and avoid these problems next year ;)
