Wow ! I never thought an old game like this is scary. Great game !
The only thing I hate in AITD is when a monster hits you and push you in a corner. It's very hard to hit back while the monster continues to hit you like crazy.
I noticed that sometimes when I start the game, the music doesn't work. I simply restart DosBox and continue until the music works.
If the game runs slow on your PC, increase CPU cycles (CTRL-F12) until it runs fine in DosBox.
As for saving games, press ESC (It brings you to the main menu) then choose Save.
