Analysis
This problem gives us an encoded message along with the hint:
Base 32? Sure.
Base 64? Yeah I know that one.
Base 2^16? ?????????
Solution
The first step is to find that 2ˆ16 is 65536 and, given the hint, the decoding will likely involve Base65536. Using an online decoder for Base65536 does not give us a useful result right away, so more steps are required.
Putting the message through CyberChef using the Magic recipe shows us that the message is Base64 encoded. Repeating the process for the newly decoded message suggests that the message is Base58 encoded. Once again, it suggests that the message is Base32 encoded. And one more time, that the message is Base85 encoded, which finally gives us:

Although it doesn't look like much, all these characters are valid UTF-8 characters and, therefore, can be decoded in Base65536. Passing these values to the decoder gives us:
