Permitted Unity Middleware?

Greetings,
Looking forward to my first LD solo entry.  I plan on using the following tools:

Game Engine
 Unity3d with:
2D Toolkit (https://www.assetstore.unity3d.com/#/content/908)
Polygon Tool (https://www.assetstore.unity3d.com/#/content/1032)
iTween (https://www.assetstore.unity3d.com/#/content/84)

Are commercial libraries such as 2D Toolkit and Polygon Tool permitted?  Obviously we don’t want to release their source.  I am getting lots of mixed responses when searching for this answer.

Audio
sfxr
Audacity
Linux Multimedia Studio (LMMS)

Art
Paint.NET
Photoshop

 

Thanks and have fun !!

IMO those plug-ins are fine. You can’t deny Unity today and plug-ins are a way of life with Unity, and most are relatively cheap.

Yes, you can use those. They are just libraries and all publicly available (free or commercial) libraries are fine.
