okay that's working! how did you do these low fine res?
In the editor there is the real resolution of the sprite, I marked in blue on the screen and the one that will be on the stage I marked in orange, on the stage the sprite can be scaled.
You as an artist drawing in raster graphics should always draw your characters as high resolution as possible, you can always reduce it.
After the first prototype is ready, you can pick up the minimum resolution of the sprite at which it will not look terrible to you. After that we insert this image into Construct3 and if the sprite turns out to be larger than necessary it can be reduced mashtabirovanie (orange on the screen) after that you need to see how it looks on different screens, I always look on a computer and on mobile.
These tips are NOT about pixley art or vector graphics.
