hi I got a brand new tamagotchi ocean a couple of months ago. i played with it a little time, then i kept it in it's package for some time because it's extreamely hard lol but when i got it out i found that now i need to push the buttons very hard in order to get them to work... has this happened to anyone? what can I do to fix it? I really like the ocean and I don't want to order a new one...
