Yeah that is an actual chip tune on the PSG
as for the walking speed, once its fully bug fixed (As in, that one random ghost sprite stops occuring) and its built entirely for CD, a bunch of optimizing is going down that will increase the speed of the game. Its too hard to play test it at fast speed.
and the little guy wont look as seizure like once i finish adding more frames to his walking animation.
its 2 frames back and forth right now hehe
as for 2 player option......
the next game we make (the arcade pack) is going to have 5 player Insanity death match in it....
