Pretty cool, loved the world building, the island was well crafted with lots of verticality, and the mystery is super intriguing. Did take me a little while to figure out even with the detailed instructions xD I'd be down for the second chapter for sure! My only critique would be having to go through all the tapes is a little bit of a chore all in one hit like that, and led me to crawling under the table and busting through the ceiling at one point, whoops. But the concept overall is great and looking forward to seeing the next chapter! 

 Playthrough is here in case it's useful:

Thoroughly enjoyable mystery! Looking forward to chapter 2!

I enjoyed the audio puzzles,  I did start the game off by backing off the pier and entering the hallways on accident, and restarted lol playthrough up on www.youtube/user/tonius42
