well since I'm pretty new to the flowlab game engine everything was more complex so if I wanted to play a new song I had to assign a different block a property on each level with a new song and to remove the song on the next level. I would love to add moving bits but I sadly don't know how. but the idea with a barking sound effect could work I would just make it happen on some of the jumps so it wont ruin the experience by playing a sound effect that covers the music. lastly I will try to add a better jump animation after the jam.
