WOW! This is really impressive, all the little details, bushes reacting when walking through them and the ground changes when you shoot the grass, objects have physics, skybox and different environments for other locations.. For nice-to-haves I'd appreciate slightly faster movement and some way to indicate directions as at times I had to go back to the dialogue options because I skipped through something important.
Overall great game, really impressive, really vibey, inspires me to make something 3D of my own. Amazing work!
PS
In the first location you can jump over the fence to the lava pool near the hill
