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 :(
Way back when “addictinggames.com” was relevant, there was a game called Avalanche. The background music (dreams of above) was an absolute banger that still gets stuck in my head sometimes. Just a simple platformer, but for some reason it stuck with me, and I absolutely need to get on a computer and see if there is a playable version somewhere.
