Aside from a few classics I'm sure you've already played, I remember playing Wario Blast and Taz-Mania fairly often.

I haven't played either one in years, so I don't know how well they still hold up.

The Moomin game is great but nobody talks about it. The two Survival Kids games are incredible as well but damn they can be depressing. They really out a full on survival game on a Game Boy. Complete with multiple endings, open world and hunger and thirst mechanics.

Probably doesn't hold up anymore, but no one really talks about "Kingdom ~~Conquest~~ Crusade". It's like a really tight minimalist version of the combined live action melee and big battle strategy of the Dynasty Warriors series - compressed to fit on a classic Gameboy.

I had an Itchy and Scratchy game (from the Simpsons). It was a mini golf game that was a lot of fun.

I only ever really had the basics with my Gameboy sadly, but I had a lot of fun with Pokemon Red and Zelda Links Awakening (which I prefer to the DX version where they removed the fun teleporting glitch). Now I went this thread for other systems like PSX, lol.

Vegas Stakes - simple casino games, perfect time-killer for the format.

Wendy Every Witch Way - concept of reversing gravity has been used in other platformers since, but this might be the OG, and is very solid.

Cosmo Tank. Got it as a gift from my dad and loved it when I was a kid. I may have to revisit it myself.

Rebelstar: Tactical Command, In a nutshell it's X-COM for the gameboy advance.

You know what was great and gets no love? Q*Bert for GameBoy was a really solid game that had a LOT of stage variety and even silly cutscenes. Literally the only thing it was missing was color. Highly recommend.

Falling sand games, specter supreme, escape velocity, gyromite.

I didn’t have a Gameboy, but I did have an Atari Lynx and I would say for Atari it was Batman in color.

Quest for Camelot was a banger. I think it's in NSO actually. The sword swing sound effect is burned into my DNA.

Great Greed!!!

Lighthearted RPG with a really neat combat system, funny writing, and food puns everywhere! So awesome and I never see anyone talk about it.

Shout out to Hungry Goriya for her excellent review on this gem.

Avenging Spirits. When I was younger, a friend and I loaned each other a bunch of our games. Sadly, he ended up moving away before we managed to swap back, and he got the better end of the deal when it came to the games. However, I did get left with a copy of Avenging Spirits... the game is a bit strange but its very fun and the sprite work is just adorable.

The game has you playing as a spirit who can possess enemies. You start off with a few you can possess, and then you gain more choices as you progress. Or so I believe... I wasn't all that good at the game back in the day, so I don't remember getting too far in it.
