Im not shure if its the apps fault

OMG I LOVE THIS APP SO MUCH I downloaded it to my iPad and as soon as I got it Ive made wonderful creations but the day after I unplugged my iPad from charging and it was still had the little symbol for still charging but it was unplugged so I played on my iPad for a few minutes but the charge stayed at 100% and it usually looses 1% every 5 mins and I played for about 10-30mins then I turned it off I couldnt access wifi and could not reboot it then I left it off and went to turn it on and the password wasnt working so I turned it off and now its not turning back on
