Well, Here is a screen from Sketched.

I used the vaving flag effect from thunderbolt to represent the heat in this first level

the story is official except for the grandad part. you are alone, get trapped, your pencil for your notes somehow fuzes to this sacred artifact and the theme of a pencil engulfes all of the levels, hence the pencil you ride through each level. and the DOOR to the way out has 12 locks and you have to find the paintings and retrieve the keys

well, the gameplay will mostly consist of both exploration(the gigantic pyramid with a kinda aztec design where yoy first enter and you have to search for the pictures) and adventure and dodging (the actual painting levels.)
