A:AnswerBasically every game is compatible on both systems, the outliers being games that require the use of joycons, and even then they will still work on the switch lite when used with a separate set of joycons. The Labo sets wont work as most are designed for the original switch. You can also find this answer yourself on the products page as most respectable retailers will have specifications/details about a game's supported modes; switch lite in this case counts as handheld.
TL;DR This will play on switch and switch lite.
A:AnswerI would say probably I remember playing the original one ( back on Nintendo 64) when I was a kid I didn’t know what I was doing but I just liked taking pictures of the Pokémon but i don’t know what 6 year old are into no a days xD
A:AnswerNo there was suppose to be but they shipped the game without the stickers. I had ordered to be picked up but received by shipping before I received the message to pick up. It was all messed up. I didn't go to pick it up and cancelled the one in the store so those stickers got cancelled with it.
