Would like to say great work on this.

And you might want to consider making the charging station have an inventory slot / space of 1 so you can "Store" the portal gun on it.

Also, I don't know if this was said or planed already, but how about color selection upgrades with names like Portal Color (default), (Atlas), (Peabody) since those 2 had different colored portal gun portals.

Hopefully I'm not pushing you do to anything you're not comfortable with or putting in more than just my 2 cents.

Original design was a charger per gun but that seemed annoying to me so I made it a range around the charger that you plug the gun into. Color selection was also a thing I considered, the hardest part is the UI for picking a color, the artwork can take any color (it’s all gray scale)
