Might be easy with buffers

So you want to replace the default cursor?

Yes, the native cursor icon with various shapes. Native OS cursors have some benefits over software texture cursors in some games - generally they are superior but won't work for everything you want to do with cursor images.

We can let user set cursor based on a Defold atlas texture.

We can let user switch to standard OS versions like hand cursor too.
