this is the polish update, I mostly added stuff that needed to be added.

changes:

• made the windows display name "Space to Breathe" instead of "space_to_breathe"
• added an icon
• added a pause menu
• fixed bugs with saving and made save sizes more compact
• added ability to zoom camera in and out
• changed cursor to a cross ( + ) when holing laser drill

this update is the first to implement play tester feed back and I think it really helped guide the direction of the update. I will definitely be using play tester feed back for future updates.
