Micromax A89 heating too much problem on playing games

I had purchased micromax A89 over a month ago. This phone is good as per it's price tag and i wish i could have wait a bit more further to read it's review and all the drawback. The main problem and only the problem of this phone is it get heated up very quickly.

When i play games for more than 15 minutes it starts heating up like a hell. i can feel it heat same like our bike silencer which get heated while drving. i am feeling very afraid, if it gets more heat will it get blast. Tell me the answer for my query

That is common site with smartphones, may it is hot summer which is even increasing inner heat. You should be careful.. but if phone is heating but not battery then I don't think it can blast off :)
