Hi! Thanks so much for picking up the whole bundle, I really appreciate it.
Just to clarify, these assets aren't a traditional fixed-size tileset, they're individual elements separated by category with a transparent background, made to be worked with and resized individually rather than matched to one single fixed cell size. That's why it's scalable for multiple resolutions, you can resize each piece to whatever grid size your project uses.
Here are some quick steps depending on your engine:
Unity: import the sprite, set the Sprite Mode to "Single" (or "Multiple" if you're slicing manually), then adjust the Pixels Per Unit value so the sprite matches your desired in-game cell size. Keep Filter Mode set to "Point (no filter)" if you want a crisp pixel-art look.
Godot: import the sprite, then in the Sprite2D or TextureRect node adjust the Scale property until it matches your tile/cell grid. Make sure Filter is set to "Nearest" in the texture import settings to avoid blurring.
GameMaker: import the sprite, then resize it directly in the Sprite Editor or adjust the Image Scale in the room/object settings to match your grid size. Disable smoothing/interpolation for crisp pixels.
Since every piece is separated by category, you can scale each one independently to fit perfectly with your own grid, there's no single fixed cell size you need to match.
