Yeah, it is just looks ugly after rotation whatever I’m trying to do or use.
Even spriter screw it up which is designed to rotate sprites and pixel art tools which is made specifically for pixel art 
Seems like if I want to rotate something better do it in GDevelop which is going to require to make the objects modular. A single object on the screen would be made of multiple parts and I could rotate the parts whenever and as much as I need but it might would consume too much CPU in case there are many “modular” objects 
Or I could make the actual pixel art bigger and I could scale it down in GDevelop to the size I need. It would make the distortion less noticeable but it may going to consume too much memory, since I’m aiming to use pixel art not bigger then 60x60 pixels but to make them look good even after rotation it would require to make them something like 200x200 pixels and scale it down to 60x60 in GDevelop. If I rotate it and scale it down in a paint tool it is just ugly so at least one thing rotation or scale need to be done in GD to make it look not even good but acceptable.
