Yep! If you collect the coconuts from the palm trees and get the coconut launcher, you can take out the tiki guy so he stops shooting at you.
I have a bunch of different puzzles jotted down and the next update will include more as well as opening up the maze some more. Glad you found them to be a little challenging!
I've been rethinking the first person system quite a bit lately. I wanted it to be similar to Arx Fatalis with the separate combat mode/interactive mode, but it's not really working out so far. I'm still toying with it.
Next update will get rid of using Rigidbodies for the pickup/dropping system because it's been nothing but a headache to get working correctly.
Thanks a lot for playing and giving such useful feedback! I'll be trying out your demo as soon as I have a little free time!
