Back in the day, I completed this on the GBA. But that was about 8 years ago, and it is such a good game that I really got into playing it again when I got it for free on my 3DS.
It is still excellent, and still the best Wario Ware title. Not that the others were bad – just that this one is the most pure. Or something.
Completed it today, and found it far easier than I remember it being on the GBA. I suspect that’s because part of me remembered what I was supposed to do in each game. Or I’m just a better gamer now (not true).
