If one were to make custom LARGER sprites and tiles, and drop them in, is there also nothing else that needs to be considered for all of the rest of the games functions to look and act properly? Is there no other considerations that need to be taken for these things being brought into a project where the tilesets (and everything else) remains the same? Is it really as simple as make them taller and drop them in and everything looks and acts just fine with the rest of the vanilla game?
So the idea of the taller sprites I see people making hurts my head a little bit. I hope this would be the section where the most people with this knowledge would frequent.
