I made this initially for fun and to learn more about python and pygame. Thank you for trying it out and let me know if you have any suggestions

Controls:

[-,+] --> change row of tiles

[1-9] --> change tile

[r] --> rotate tile

[s] --> save file

[esc] --> go back

[enter] --> finish typing

To use custom tilesets:

1. png has to be 72pixels across and a multiple of 8 pixels down
2. put the png into Tilemap Editor/_internals/graphics and name it 'tileset.png'
