Thank you for the reply, i'm sad you couldn't enjoy the game due to the said issues. I'll make a downloadable .exe and allow the option to disable post processing effects since that may improve performance, i'll also fix the music.
Hey, good news the game is now smoother and available on pc, mac and linux..that should ensure a smoother performance (p.s : The music no longer restarts, it continues on death and in-between levels :) )
