This game had some fun ideas to me; both high-level, narratively (it's not quite clear if the heroes are "animals" but they're sentient enough, and imply a rich history) as well as low-level. You control a small team of characters, each with unique abilities that can be used in various scenarios. At the game's most challenging moments, it asks you to swap mid-air in order to perform jumps in a certain way.
There's some good character moments as well, showing vulnerability and growth from each of the heroes. The only bit I didn't like as much is the navigation. Much of the game revolves around use of blood vessels to navigate, since it all takes place inside of a living being. As a result, when one character says to "head East", they sometimes mean "Wander in an indeterminate direction to unblock a blood vessel around the middle of the map so you can get an ability that will let you unlock a path that warps you out East."
