Wow, your game looks really really good!!
Thanks for all the help! I did set the tile size to 48 and added some layers and
that already works way better. For example I use a road decal (the complete thing with the shadows around) and then I alternate one piece on layer 1, the next on layer 2, so that they overlap. Looks quite well! :-)
The actual map size (number of tiles) can be set by user preference, right? if I multiply the tile size by 1,5, I should probably do that for the map width/height likewise.
Also with number of sprites you mean setting those to 8 (seems to be the PVGames default), right? https://docs.freemmorpgmaker.com/en-US/configuration/server.html#sprites
@Smoot: You mean besides the decal tile sets those are usually 32px?
Thanks!
