Just have a very good time playing your game ! The retro feeling (and the music) were amazing !
The only thing I can say for criticism is that I would make the (awesome) background music reverse when rewinding, such as setting the pitch to -1 for example, replacing the rewinding sound effect you've included, this would be perfect !
Thanks for the comment! While rewinding the music would be awesome, I figured with how frequent the rewind is used, the same parts of the music would be played over and over again. This also creates problems because enemy spawning is based on the music loudness. So I instead made it the rewind sound to provide a brief relief from enemy spawning while adding audio feedback. Thanks for playing!
