A bug may happen when you click several times too quickly in the middle of the screen (the area that activates pause/resume) in the browser version of PEXERS GALAXY. This type of bug I never knew until it's in the run. A bug report helpes a lot. Thank you.
I tried many ways and compromised it to the least devastating bug which is to get the sound inturvened every moment. If this happened, please re-start the application. I keep look for the way to solve this problem.
