In episode 31 you created the world units to tilemap mapping. But you used 1.4f as a tile heights. I feel that value was arbitrarily chosen. A better mapping would have been 1.0f so a tile = meter. I feel this will make the world simpler to understand and work with.

Second, you can have the character be 0.75 x 0.75 wide, such as he won't clip entirelly in the tile above it. Call it the character base, as such it can be used for pathing.

We could have tile side = 2.0f and boy height =1.4f so that he is smaller than the tiles.
