There's a lot more going on in this “walking sim” than is apparent at the start, both naturally and supernaturally. This contradicts the fact that, aside from the animals and the ghosts of the past, you are alone. Kona works hard to create a sense of isolation, making the experience much more effective if you're not surrounded by people helping you solve the puzzles or arguing against using a crowbar to fend off wolves when you have a gun in your possession (although that it is very sound advice).
I can therefore recommend Castle of Heart only to those who are up for an extreme challenge or who have something to prove to their punk children (or punk parents). It's a beautiful game and the development is almost flawless, but the rewards don't come often enough to help you past the game's brutal difficulty.
The fact that each level can be overcome in about 15 minutes or less makes Bridge Constructor Portal great for portable gaming on your Nintendo Switch. On the go, the convenient touch controls carry over from the mobile version (tap and drag to place your struts, zoom in for precise placement, etc.). Docked mode, however, is a bit more cumbersome.
