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)
