Junder, we genuinely appreciate the detailed feedback.
Given the time, the changes I would have made to the game would have been:
1. A little more intuitive combination lock puzzle - seems the most people get stuck there.
2. More time with the statue puzzle, I would have removed the space-filling doubles of animals and found a better way to represent the larger animals than just using their heads. In addition, the collision is rough there.
3. We ran short on time and had to skip on sound -- but I 100% agree with you. Sound on the gravel floor with the waking guards came up multiple times in our play testing. Depressing pressure plates would have been a great touch as well, especially for those not sure whether the statues are in the correct spot with the statue puzzle. The footsteps would have been a nice touch as you mentioned.
Thanks again for the time you invested in our game and providing the feedback. That means a lot to us!
By the way, YOUR combination puzzle in House had me going for a minute, lol. Big fan of your game.
