Yea it's a platformer. It's more like Super Mario 64 where you have different missions in the same world to collect emblems of courage (in placement of stars). Plus, there's also some secret eggs in the game when you hatch them, you unlock secret GBA connection mini games. I unlocked Puyo Pop! as of now but I had to take the game back today.
The other games include a GBA version of NiGHTS Into Dreams, and this billy hatcher shooter.
