Answer 1

Looks like the texture is set to GL_WRAP. Try GL_CLAMP_TO_EDGE instead.

Answer 2

In Game::loadImage, after your glBindTexture call:

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);        
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);        

Your current setting is GL_REPEAT, which is the OpenGL default.
