Yes you can surly do this. Just layout your graphics and use rect and containsPoint in your update()

Thanks for the reply @slackmoehrle . Yes it will be good to detecting the collisions with obstacles but in case of jumping on to the platforms i have to use the same way or any better ways?

Yeah touch events and update()
