With no tutorial I have no clue what is the goal of the game, The score was -2000000000. The music button made the music louder and the mute din't work. 

try to do webgl instead

Not sure what im doing in the game. Its just Tuesday (as of this comment) you have the whole rest of the week to either make a good tutorial or rethink your approach.

Music button increases the volume and mute doesn't work.

I only randomly clicked the tape to see the texture changing (rewinding)

overall, not a bad clicker game concept

Bugs i've found:

• Score randomly gets set to Integer.minvalue
• Buying pencils or cassette players doesn't change the x0 into x1 and beyond
• Pencils and cassette players dont show the tape rewinding animation
• money isn't subtracted when you buy items
• Mute button doesn't work

Its very early to be submitting something, especially if its in this state

Things id recommend adding (if you have time)

• More upgrades
• A background that isn't the default Unity2D blue
• webgl build to avoid download (i noticed you had problems with this, maybe ask the unity forums for help)

Hi! Not bad, reminds me of Cookie clicker, just a couple of things:

• Display some visual information about how much rewinding of each cassette you've made, like a percentage number or a fill bar.
• Maybe some particles on each click to let the user know that he is actually clicking.
• Some description about what the pencil or the other things on the right bar do.

But good work :D
