Yes, you can get into the mausoleums if you find the required emblems to open the doors. They can be found digging graves. It is difficult to enter, but there is a lot of money inside.

Ah. In my first attempt, I must have wandered around for half an hour without finding any graves at all. This time, I managed to find 850 gold - though every grave I found was purely by chance. Not sure how I was supposed to be finding them, but I was quite glad that the sky went red a bit later on because it made finding the graves actually possible.
I think the main problem is that you can either have a big level, or a dark level. Having both just doesn't really work. You did have a map, and added some distinct locations to help orientate, but all of the graves I found with anything worth inside them were nowhere near these locations so it was not of any real use. The player doesn't really have many issues finding the mausoleums, since they are big and bright. What they need are guidance to the graves.
I think the best idea would have been to concentrate the map down. Perhaps a quarter to an eighth of its current size. Have a few hidden graves, sure. But stick most of them in groups in graveyards - and instead make the punishment for digging up the "wrong" graves a lot higher. As it currently is, the graves are so hard to find and the punishment so slim (a single ghost spawned, maybe) that I dug up every single grave I came across, without ever really reading the notes. After all, if I walked away from a grave there was a very low chance of ever finding it again.
I would also recommend fading out the ghosts at long range, they were totally harmless as they were extremely easy to avoid. At least this way you might stumble into one, or it might sneak up on you. The red guy, not sure what his deal was. Seemed to be attracted to my location occasionally, but I just avoided him until he gave up. Until I screwed up and he instakilled me that is. Not sure what his deal was.
Thank you for your feedback, we really appreciate it : ). Actually, we agree with many of your points, specially the difficulty of finding graves. We did not intended to make it that difficult but some problems appeared during development and we run out of time to make changes. In the future, we might update the game and fix some of those problems.
