This game is best played with 2 players which means you will need the original Nintendo Switch.
SPOILER AHEAD???
It can be played with just 1 player but it's kind of a pain. You will have to control both characters at the same time with one being moved using the left side of the switch and the other one the right side. With the ragdoll like mechanics the game uses, your character will move all over the place, will trip over everything and anything and at the beginning it was hilarious but after a while it gets infuriating after the 100th time your character trips over a skateboard because you confused the left side character with the right one.
The game follows a plot, which is fine, but there are these little mission that you HAVE to complete in order for the game to move forward and gety you more of the rescue missions (which is the whole point of the game and also the fun ones). The problem with these little missions is that they are boring and anger inducing (the missions in question are the ones where Doctor what's-his-face adds some features to the ambulance (which are useless, 99.9% of the time you won't need them and are more of an annoyance than helpful) and you have to race something or someone. If you don't complete that mission, you won't get anymore of the rescue missions. Plain and simple as that. The game effectively blocks you. Said races are rigged and you have to repeat them multiple times over, over and over again in order to progress (it stops being fun after a while and it only angers you). There will be more cars in the streets, more stuff in the way that will block your ambulance and stop it dead on its track while the thing you're racing goes 120 mph. There is one mission that I had to repeat 10 times (I count them). Right now I am "racing" (is it really racing when the other thing/character has a few seconds extra than me because the game won't let me accelerate until the speech bubble disappears and it's going considerably faster than me?) a helicopter (A HELICOPTER) that goes so, so fast and does random and quick turns (faster than the ambulance, obviously), they have nothing blocking their way (unlike me with the stupid amount of cars the game generates during these races, the buildings, rocks, billboards, etc) and I have failed that mission so many times I am about to kiss the game goodbye or give the switch to someone else to see if they can pass that level for me before I throw it across the room. Like I said, I can't skip the mission, I am affectively being road blocked in my own game that I bought with my own money. I am just replaying old missions over and over again to satisfy the urge but that won't last forever.
This game certainly isn't for children since there is no difficulty setting either that might make those missions easier.
Like I said, if you're playing single player everything is more difficult to manage.
The good? the graphics are beautiful and colorful, the rescue missions (when you can play them) are funny and you HAVE to use logic in order to rescue the hard-to-reach dizzies which makes them last a while allowing you to really milk the game (although you have a timer to consider) but that's it. If not for those obligatory and ultimately useless missions that block you from playing the rest of the game until you complete them, the game would be a 5 star for me.
