Tileset for prototyping 2D Metroidvania games

Hello,
Thank you for creating this tileset! It's very appreciated!
I also wanted to mention that, for future tilesets, it might be helpful to arrange the tiles in a grid pattern where each tile fits exactly within the size of the grid squares. For example, the first screenshot is the tileset provided, unaltered, on a 64x64 grid. See how they're crossing over the grid lines? In the second screenshot, I rearranged the 64x64 tiles not only to fit within the grid lines, but to also help me identify each tile's purpose (i.e. wall tile, corner tile, inner tile, etc). This way, as far as I know, it helps with using tiling programs/features if the tilemap you use is already arranged in a grid-like pattern. 

I hope that made sense...

P.S: I'm not an expert at this. I'm just going by what I've learned so far and what has worked for me. I also hope that I arranged the tiles in the way you had intended. The corner pieces were particularly hard to figure out... ^_^;

thank you so much!
