Platform game sizing

Hi, not been on the forum for a while due to life events. Anyway, working on a 2d platform game and worried about the layout size. The layout is currently 4096 (w) x 1024 (h) with a grid size of 32 x 32. Thinking of making it wider for a longer play through and adding more obstacles. My player is 32 x 32 and some enemies, I try and make enemies in proportion to the player and layout. Am I heading in the right direction ? Thanks

You can have massive layouts without too much trouble, so I wouldn't worry about there being a practical limit. Just make sure that there isn't tons of logic like collision detection or physics simulations happening all across the layout, or things might slow down. Also be sure that User Render Cells is enabled on your layers.
