It's a good game, even competent, it's one of the very few Super FX games that has aged reasonably well, but it still has some problems that because of the low polys make it very difficult to know what the enemy is, what the shots are and What's your partner, it's a game that you need to be focused on in all directions,
But thank God the tiny screen helps a little, you can also do alternative routes, but I only did the main one, there probably aren't any alternative endings nor does the final boss change, but honestly I'm satisfied with having done just one route.
