You can finally jump now, what a concept. The concept of swap force chars was such an interesting twist and also led to some interesting gameplay options. The balancing is such a joke, with some Swap Force chars being so OP that it does kinda make the game feel pay to beat it more easily. The 100% completion aspect is kinda reliant on Swap Force chars, but you also need Giants as well. At least for the dual gates, you can just bypass them with a 2nd controller and 2 skylanders of the elements rather than relying on a Swap Force char.

This one wasn't as great as the last 2 titles and started the turning point of the quality of these games but the game is not half bad with the new swap mechanic kinda like having a pokemon with multiple typing's giving the game more advantages and convenient timing with the acquired gates and minigames but this also means that the opposite can also be said with how if you don't have this particular swap character to do a single minigame you'll miss out on some treasures to get, which unlike the typing barriers, these feel more scummy to only allow a small amount of the entire roster of swap skylander's in order to access these minigames it requires more payment to 100% it.
