First play through and found some bugs. Using an Xbox controller, running while holding RT and pressing Y put me into some kind of 'out of body' fly mode, where I could zoom anywhere, including into the locked temple. Pressing A put me back into my body. Also, the game abruptly quit when I got back to my boat after retriving the idol, probably because i was fratically pressing the use button, thinking i would need to in order to actually get in the boat. Didn't get a good look at the monsters as I was busy fleeing for my life.
Second playthough worked fine. A more threating monster and something to add a little tension in the first part would help to improve the atmoshere.
Over all a well done first game. I hope you continue to create.
