The DS version of this game restricts how many objects are on screen at once. I have no idea why they did this, they're lines. It shouldn't be that graphically demanding. The story mode essentially turns Line Rider into a puzzle mode, which is interesting at first but gets kind of boring pretty quick. The style of the game itself isn't great either and the CGI cutscenes are dreadful.
This game overall doesn't do much different from Line Rider at its purest form. I was really excited about it as a kid, but that was because it was something familiar.

I think this game is a fairly good game. It's one I don't see myself coming back to (although I did play it TWICE, once on the 3DS and once on the Switch). I think the allure of it was quite honestly what Tomodachi Life was all about too, which is putting in people you know into the game as characters and seeing how they interact. The interactions in this game compared to Tomodachi Life however are very basic, so this ends up being a very status quo RPG with a few changes to the basic formula/mechanics of the genre.
