So, I was gonna recommend Super Mario 64 DS to someone who's not familiar with 3D games and I figured a nice hack/cheat for them to use would be to not have limited time underwater. I realise it might be difficult to make since the air meter is connected to your life meter so you might end up becoming invincible, which makes it too easy again.
I've already checked the cheat database you can download with twilightmenu++ and romhacking.net.
