Personally think this is one of the underrated games of the M&L franchise (shocker, no one has said this before!)

I actually loved the combat combining both Mario/baby Mario & Luigi/baby Luigi attacks. And still being able to continue the fight if one of the bros dies.
The puzzles weren't inherently difficult but provided enough of a challenge for me to want to be always looking for secrets whilst using the baby bros.

Music also doesn't get a lot of love, which i think isn't entirely their fault, you have other games with a lot more memorable tracks.
overall i love this game and i pray for alpha dreams return.
