It's very polished and very addictive.
Highly replayable,
and some super hard optional races at the end.
Loved the bestiary section,
it's fun to revisit the various areas and try to complete it.
它非常精緻並且非常容易上癮。
具有很高的可重玩性，
並且在結尾處有一些超難的可選比賽。
喜歡動物寓言集部分，
重訪各個區域並嘗試完成它很有趣。

Metroidvania games aren't terribly difficult to come by, but there's a clear trend toward the Souls-like subgenre. As someone who doesn't play games because I want to be constantly embarrassed, I appreciate being able to find one that has a hook other than severe difficulty.

Options > audio > Alternate Battle Theme ON. This changes the wild encounter music from the default track (sounds like a tutorial) to the Infinity Arena track (fast, energizing, has a memorable opening sting).

I could probably go on about Monster Sanctuary for an hour or two, but I'll keep this review short and to the point. The game's got simple yet charming monsters. It's got an addictive combo system, in which each monster's actions increase a multiplier your last monster can exploit for massive damage. It's got absurdly deep monster customization featuring varied equipment and impactful skill trees. It's got sprawling interconnected environments to discover, and every new monster can help you get past obstacles to explore new parts of the map. It's got decent puzzles too, although they're pretty much all variations on "pull levers in the right sequence to open a path." It's got an endless gauntlet (sort of like the Battle Tower in old Pokemon games) where you can steamroll the first three encounters and then start fighting for your life by the fifth, earning useful items for your trouble. And finally, Monster Sanctuary's challenging—while the wild encounters and champions (boss monsters) are usually pretty easy, you'll also find yourself pitted against characters who have their own monster teams, and those fights are the real deal. The difficulty cliffs they presented in the early game forced me to optimize my monsters' kits and to be intentional about teambuilding and strategy, and it was always so rewarding to find just the right adjustment to let my team pull through. Add to this a star-rating system for the boss monster fights, which you can replay at any time from the hub, and there's plenty of strategy to enjoy. It's looking like I could 100% the game before the 100-hour mark if I hustle, which might upset some RPG buffs, but Monster Sanctuary is still one of the most dense and satisfying games I've ever played.
