Mine has to be Dragon Quest: Rocket Slime, a DS spin off of the Dragon Quest series that sees you playing as a slime operating a tank and rescuing the people from your town. You run around the overworld, collecting items to use as ammunition and saving money to upgrade your tank. The art and music are just as great as you’d expect from the Dragon Quest series. It made fantastic use of the DS’s dual screens. It’s also written for a younger audience, so a lot of it is just really silly and fun! Try it out for sure, I’m so sad there’s no sequel :(
I agree, I really wish I could erase it from my memory and play it again. It’s not an obscure game but I think it’s hard for it to stay relevant on social media and in the zeitgeist since it’s both short and not a game you really replay.
I’ve tried to recapture the feeling of playing it by watching others play but most people approach it poorly and impatiently and just end up guessing too much.
If anyone else is in the same boat the best one I’ve found by far is MangledPork.
