Speeding up your code

i just made a small little game and it runs great on my computer but i noticed when i run it on a 486 it runs pretty slow at times. i was wondering if i post my game here if anyone can tell me what i can do to make the game run smoother. I have quite an idea why its slow on a 486, its because i dont use bitblt i move image boxes around the screen instead of drawing it by code. anyway is anyone willing to have a quick look at my game and tell me what i can do to speed it up without getting rid of any features? thanks ahead of time.

Thats one point, but if you need better performance take DirectX or better: Code in C++

isn't a 486 a bit optimistic?
anyway, use BitBlt to speed up the graphics, or use DX. But I doubt a 486 will have graphics card that's compatible with DX

will it be hard to convert about 20 imageboxes to work with bitblt? most of them sit in place but are animated but the character you control moves a lot so is bitblt ok to use in this case?

You don't have to convert anything... Look at some examples and you'll see that it's nearly the same like with images (But even faster ).
