Final Fantasy R

I really, really don't want to be "that guy", but while I see what you're going for here, it really does not work so great. I strongly suggest finding some tileset rips from FF1-3, tripling the size, and using those. They won't look great blown up that much but they'll look a lot better than what you've done here, which looks like shrinking the RTP tiles and then blowing them up again.

Alternately, you could use the grid size plugin and work with the tiles at 16x16 and then use a smaller screen resolution and upscale that. This would probably produce the best look but it's more work.

Like I said I don't mean to belittle your project and I think a dungeon crawler featuring various FF characters is an interesting idea, but you gotta do something about the graphics if you don't want people lambasting you. :/
