Yes, they are just minor bugs that won't stop gameplay, yet annoying for such a great enhanced remake! 
One of the bugs I've noticed is that starting a new adventure, skipping intro, there is no ambient/music sound outside the mansion, at least until someone enters the mansion. From that moment on ambient sound and music will play fine also outside. There is NO bug letting intro fully play.
Another bug is when trying to use some objects with each other: original game ALWAYS gives a typical answer "I can't do that/It won't work/etc." but MMC sometimes gives no output at all. E.g. try to enter the kitchen and use anything in the microwave oven.
