Stela feels like a golem, crafted from the bones and sinew of better titles. Sometimes, this can be a successful experiment: Darksiders, for example, may not contain a single unique gameplay concept but manages to forge its own path through its worldbuilding, characters, and art direction. Stela accomplishes no such feat, and so I spent most of my playtime wishing I was playing its inspirations instead.
Neal: It's absolutely jam-packed with features and if you're someone who already has Shovel Knight, it's a heck of a free addition. As a solitary game, it's a much harder sell. Like you said, it's more of a curio or bonus than something that could stand solely on its own.
