Portal Picker Update 1.1 "Busy Sky" was released

With this update I wanted to fix a few gameplay issues regarding progression as well as add another portal type. My intention is that with each update there will be a new portal that adds features from one of my other games. The more games I have in the backlog, the more content I can add in the future! Here is the changelog:

- Added new portal which references my game Busy Sky 
- Added new set of upgrades
- Added sound effect for buying upgrades and buildings
- Added weird background artwork
- Added chilly background music courtesy of AIVA
- Adjusted late game upgrade prices
- Changed artwork for first mirror portal upgrade
- Fixed (hopefully) a bug that caused golden hand to get stuck in a corner
