Hey!
Thank you for the response. What I meant by different pixel densities is that for example, the outside ground tiles are 32x32 where as the mine tiles are 48x48, another thing is the character size vs the tent or signs and so on, a lot of things have different pixel densities making them have different sizing by default and when scaled, after being placed next to each other the look very off (like from 2 different games).
What I meant by padding is that I had to add a 2 pixel wide line around each side of every tile so that unity doesn’t have visual glitches, here is an example of that:

In terms of the transitions, I mostly had issues with corner pieces, here is the tile pallete with additional stuff I put in:
