Thanks for having a look.

VilleK:

I have no idea what's happening with your keys: I am using the usual DXInput for reading the keys and this is the first time this has been reported. So you are saying that 2 movement keys cannot be pressed at the same time?
The difficulty is something that is being worked on right now. The point of the level designer is for someone to make a realistic and challenging level set. We are in the process of taking the original roms apart to try and get the original level data.
You will find that the game gets very difficult as you progress - what level and score did you reach?
The hiscore screen remains the original "slap together" version. New screen is currently under development.
