Fruit spawn considerations

[wendelscardua]

By M-Tee:

• It might be nice if the fruit spawns at intervals that results in the bobbing animation to be offset from each other (i.e, whilte one fruit is on high, the other is on low?)
• I think fruit should spawn frequently enough that there are often 2 fruits on screen.
• If the player is at 0 energy, should we influence the location of every other fruit spawned to be closer to the player?
• a reminder that, if we haven't already, make sure that active fruits don't spawn on the same row, for scanline conservation.
• when fruit disappears from not being picked up in time, it should flash on/off first, I guess at the same rate we use for the energy bar (on, (off, on, off, on,) off)
