Wow, you really have made progress with BK2! I have a quite important request for the gameplay. Alot of people that saw the first game said that the physics of Timmy seemed a little bit to unreal. Even though I agreed with those comments I defended your game with "It's supposed to be like that". But after playing the game more and more I have to agree with those people. A little bit of "jumping up and when starts falling you fall little slower first and then fall at full speed after a short while". I tried to find something to demonstrate what I was meaning on youtube and something like this:
.
I have also played the game on my PAL system, just to make it a bit easier, and every time I try it on my NTSC system I think the game is too fast! Perhaps even som accelerating physics would take away this feeling. I mean that you gets to the fastest speed after running a little bit. Now you run at the same speed all the time. I am not talking about that it should take like 5 seconds to gain speed, just a short time, to make it feel a little bit more like in Mario etc.
Another thing that would be great in some places would be a sneak function, holding down a button or something, alowwing you to go forward at half speed. Taking it easy sort of...
How many pixels are Timmy moving each frame right now?
Anyway, keep up the great work, and I am really excited about this sequel!
In-game maps are really good ideas.
