Night Creatures can be fun under the right circumstances, like if you commit yourself to beating it no matter what, like I did.
Although the collision is broken, its not much worse than Ninja Gaiden NES.
The graphics aren't terrible, its just that the game as a whole is so obviously unfinished.
It doesn't go for much, so if you're a fan of the TG-16 and adventurey games like Simon's Quest, its worth trying.
Its true that there are better Turbo games, but you can always say that there are better games when talking about any title.
I like it, so its possible that other people in the world may also be able to appreciate it.
