Hello.
I am trying to make a Sonic fan-game in GDevelop (and yes, Sega allows the publishing of fan-games, since they never monetize in any form). The first thing I needed was a tilemap for the level, since Sonic needs somewhere to run. I installed a NES Sonic 8-bit tileset from The Spriters Resource, and I removed the background in Pixelorama (a pixel art editor) by bucket painting all the background with a transparent color. Then, I tried to import the tileset (the tiles were 16x16), but it didn't work at all. It gave me an error screen, stating that there was an error importing "BetterTransparentFamicomSonicTileset.png". Then I tried to rename it to "THZTileset.png" (the THZ stands for Turquoise Hill Zone). IT GAVE ME THE SAME ERROR. Which is weird because when I imported another tileset with bigger tiles (around 32x32), it worked right. Also, my game was going to be 8-bit so I could edit the sprites in an easier way, rather than having to deal with a lot of shadows and useless detail. Now I can't create the game because GDevelop requires Tiled or LDTK tilesets for its advanced tilemap object, since I'm going to need custom collisions so the level becomes an actual Sonic-styled level, rather than a bunch of chunky squares within a blocky level that looks like something that would be built in Minecraft without mods. Could you please tell me what is going wrong, and if possible, try to fix it in the next update?
