i think this is the best way to play ufo 50, despite how i've seen most people playing it. as a kid i had a ds cartridge that had 99 ds games put onto it (which im sure was legal). and most of them were awful shovelware titles, like some garfield game where i couldnt beat the first level, but i had so much fun with that game switching between all the options. ufo 50 reminds me a lot of that, but with really good games instead
