Very unique experience, I loved how I was going in with a "aw yeah, fancy shooter!" impression and then the first in-game impression was "oh what yet another ren'py game?!" and then "oh wait what - it's ren'py but 3d?" and then slowly I figured it out.
I am extremely impressed by the part where fast sequence progression is happening. It's likely many would have let the player play the parts which you skipped, even make the player carry 'it' all the way and dig the entire hole. Making it a slideshow makes so much more sense.
