SMBX Optimizations

[litchh]

I'm creating a level with medium length, but stretched on top, so it have alternate pathes. This level has lots of moving layers and events and I'm going to create some improved NPCs included custom boss which require more. But level lags yet (I still not created improved NPCs except of rotating deadly things). I replaced some 16x16 blocks with 128x128 and stretched sizables inside the walls, so now I have over 8500 blocks instead of 10000+. Is there another ways to optimize my level more?

Hmm... maybe you can use background objects (especially 4x4 blocks big) to prevent your level become lagging. Blocks are solid and can perform more lag because they are objects that are a bit stronger than background objects.
