You said it needed more. Here's what changed.
Thank you to everyone who played and left a review in the first week. The most common things you told me, and what has changed since:
"The traps are too easy, and the early rounds repeat."
The first tunnel now has a swinging stone in it, the second a collapsing floor, and from the third round hazards start arriving in combinations. Later rounds add a fallen beam to slide under, a stone door to haul open, bad ground that swings beams at you, and deeper rock with its own look.
"The boulder wasn't a threat."
It no longer falls behind a clean run. It stays about a second and a halfback, all the way to the door.
"It got too hard too fast."
Difficulty now follows the exhibits you have brought home, not the rounds you have played. Lose a piece and it is still down there next round, the worse for it.
"I lost control of the camera in the tunnel."
Hold right mouse to look around while you run.
"I wanted to see the visitors."
They are in the hall now, and the crowd grows with your collection.
"I want to play as my avatar"
Well now you can!
Also new: your run saves between sessions, a closing bell ends a run on your terms, seven more exhibits, and C to crouch and slide.
Next up: playing as your own avatar.
If you enjoyed your time in the tunnels, a nomination from the in-game jam menu means a great deal to a solo entry. There's always room for one more exhibit!
