That's a lot of work done in 3 hours. Nice idea I struggled to figure it out initially. Music probably a bit loud for me but once I turned it down could focus on what I was doing.
Thank you very much! Glad you liked it! Yes the volume is a bit of a problem in the current gamemaker runtime for the html target. It struggles with a few bugs in the current version. I hope with the next update this is fixed. I can not change the gain in code unfortunately
