I could probably spend the whole 3 days making sure the movement is on point, but I couldn't, so here it is!
The world is actually kinda cheating, I made myself a template in photoshop that I used to generate 2k x 2k tiles and then I spawn them randomly in the world, the map is only 2x2 tiles big.
So I basically have 5 different tiles, shuffle the list and spawn first 4 :)
