Dear murks,
we are glad that you tried out our game and thanks for the comments! There would be the possibility to put a cool down on quotes to give players more time to read! Something, we'd eventually implement :)
Concerning the music. The music consists of obvious covers and their titles bears reference to them. However, besides that, the cover songs have been produced in line with the fair use clause. Meaning: lead melodies are played in different scales, baselines do not correspond to the original, tempo, instruments and overall compositions are different from the original.
All the best!
