Descend 2 Resend

My first completed game! I think this is from 2017 or 2018, I made it for a gamemaker jam, the theme was "Descend". 

Collect Rubber Ducks to sink, release them to float. Find the envelope in each level and deliver it to the blue mailbox!

Tips: 

-Jumping into water from a higher height will allow you to go deeper

My biggest fans may notice that the diver from this game makes a cameo in  "The Tower of Infinite Pottery"
