The Final Gate screenshots

Title screen

Close up of the protagonist

The speedboat is taking off

Simply shoot the things that appear

Taking damage

White lines show enemy targets that must be hit

If successful you get this cheery message...

...followed by a video of the enemies theatrically falling over

Miss and you get this instead

One projectile being destroyed

Shooting at a flying skull

Another cut of the speedboat

Getting killed

Some kind of evil duck

Game over

The Final Gate
