It's a fun game, but getting what you need fast is impossible! You can literally be right in front of the item/items you need and something a few feet away will light up green. Also if you're not in a "perfect" spot or angle it won't let you grab it. The challenges are next to impossible for that reason, over all the regular part of the game is fun, but you need to make it easier to grab items, rather than them having to be lit up as green!!
