There should be a sound effect for each mode. For the flying of the map part, I hadn't been able to replicate it. Thanks for notifying me tho. Usually the fail safe would be to encapsulate the entire map with walls like with level 1 but I seemed to have forgotten it when making level 4. Thanks for the criticism. As for the mouse issue I mentioned this to others but I really wasn't able to do much testing with different mice. I do have a tweaked version if you would like to test it. You can find it on my page but please don't change any rating I just want to make it more playable
