first game idea and character design

this is my first game concepts using Photoshop as a layout.b its a puzzle game where the character spawns on top and has to get to the bottom  whilst avoiding the enemy, and making sure to make it down there on time.

 this is the character that i am going to use, obviously i am going to update him to make him look better through out time.

and the tank is a concept of the enemy that will be constantly chasing him.
