Thanks for the feedback, guys!
Several people have said about the mapping, and I agree with you. I'm just not sure how I can improve it. If you have any bright ideas about that, feel free to let me know and I'll do my best to implement it.
As far as the ABS is concerned, the main problem with that is that I'm not a spriter. I can do really basic stuff like getting rid of bits with a rubber, but my drawing skills a virtually on the level of a five-year-old! lol. Persuading someone to take on such a large body of work is really difficult. I'll probably try to get someone to do it in the future, though.
Are there any particular point in the game where it lags, or is it just general laggyness? I know that some computers find the name-input script difficult to handle, but I've yet to find a solution for that. There have been a few complaints about the camera before, so I'll probably remove it in the next version.
Hmm... I've noticed the saving bug too recently. It's odd because in tests before it was working. I'll have a look at the script and see what it's doing wrong.
The walking speed was a difficult one, because at that speed I would agree that the player is too slow, but the next level up is a bit too fast. I'll have a think about changing it. One solution could be to not decrease VP so much so that you can sprint more. I'll have a think about it and see what the best solution is.
The tombstone cave thing was really just so that there was some kind of obvious landmark for a quest. I know it's not that obvious when you are just walking around, but it's part of a quest where you are told the cave is under the tombstone.
