This game has many qualities that make it a good candidate
for TASing. These include nice and soft graphics, music that's
not painful to listen to and, of course, a very speedy main character.
The game is not meant to be quite as straightforward as it would seem by
watching this movie, as the author takes many shortcuts that require
extremely precise jumping. A downside to this game is that the bosses
sometimes have long invulnerability periods, meaning that Zero has to wait
a bit in-between hits and cannot spam the bosses with 20 hits per second.
