Created level-1 tilemap (tmx) files with different tile sizes for testing purposes.  Currently, there are version for 32x32, 16x6 and 8x8.  I've noticed that the robot's collision point has changed.  Before, the collision triggered on the outer perimeter of the robot (player) sprite.  Now, it seems to trigger once some middle point enters the solid collision tile area.  This needs to be finalized as it affects the design of the collision layers in our tmx files.  Alex, dude, please comment
