I don't know why goto statements in C are so bad

 

It comes down to maintainability. When you use goto, it's not obvious when you are looking at a destination label, where all of the goto references to that label are. Also, goto breaks the nested structure of C, since it makes it possible to jump into the middle of a nested block.

 

For an similar example, when I originally programmed Skeleton+ I reused a label as the address of the end of the "YOU WIN" bitmap. Unfortunately, at some point I ended up moving the bitmap to a different address. So instead of drawing 262 lines, the code ended up drawing far more. So if you actually won the game, the screen would roll! All because I was lazy and re-used a label.

I just had to make a mock up of what Chu Chu Rocket would look like on the Virtual boy. The tiles are 24x24 and it fit with Virtual Boy's 384x224 resolution quite well.

 

 

Here are the tiles and the sprite.
