Lovely Blues Place has a handful of cool resources, including tileset and tileset extensions, as well as a plethora of sprites. Even though it hasn’t been updated for around a year, it’s still worth a mention because of the quality of these resources.
My favourite part of the website is actually the Halloween collection (an example is to the left).
There are 14 Halloween character sets to use. They’re cute and well drawn and, with October fast approaching, someone may be able to use them if they’re planning on creating a Halloween type game.
This is by far my favourite, the Garden Tileset. I can really see this in a garden or park setting, along with some park benches and lampposts.
The charsets and tilesets should work with RMVXA, but unlike with RMVX, it’s possible to create new tilesets and add any additional autotiles. RMVXA also has a “VX Compatible Type” option under the tilesets Basic Settings as well.
If you use them, don’t forget to credit Lovely Blues somewhere in the game, usually the end credits.
