Performance improvement for entity selection

I have just published an update which improves entity selection.

You can now both ctrl + click on an entity to select it, and ctrl + draw an area rectangle which selects all entities inside it.

Before that update it was almost impractical to use the selection feature. Now it provides a much better experience.

Also if you have selected some entities and want to abort the movement process, you can just use the clean key (default right mouse button) to do so.

Hope you have much fun using the game.

Kind regards
