If game doesn't work for someone (GL_INVALID_OPERATION, opengl error 1252), it means it's running on intel graphics, if you have external/discrete GPU, run on it. Next time try making logs more verbose, it would be hard to debug from it :) Nice game, funny and nicely done. Huge props for making it in c++ and using the tga format :D A little tutorial would help since at first run I just ran away from the starting point and tried to find the mushrooms in the forest. Also it would be nice, if there's no sound, to at least have some graphical effect that you are attacked or your picking the shrooms works, since it requires multiple clicks. But anyway, nice and fun game!
