It's not bad, but also not really something to recommend. It's the dull, reliable button mashing metroidvania you have at home when you need some comfort, and probably have something on your second monitor. Skill is not really required, as combat is determined by your level and the last time you bothered to equip the new gear drops. The first half of the bosses you can defeat by pushing them into a corner and spamming one button. At the same time the map is actually pretty big and you don't need to do any deliberate grinding to progress if you take the time to explore. The story is pretty generic and gets delivered through a couple of long, traditional lore drops at the very end. Most of the rest of it is the usual anime BS involving awkward conversations, gimmicks, and hot tubs. Localisation is pretty meh, not that there's much to miss. You even get used to the occasional lines getting cut off.

Frontier Hunter is basically metroidvania junk food. It's modelled after the Igavania style (think Bloodstained) - a standard ability gated metroidvania with rpg-lite character progression. The gameplay loop of combat, exploration and fetch quests is fun and moreish while the relativity large map is an easily readable tile based affair with pins for marking treasures and such. Level design is unexciting but not awful. It's all serviceable stuff.

On the downside this game has very little challenge, looks ok but lacks any real identity as a result of the bland environments and derivative anime designs, and has a trope filled anime story with a dodgy English localisation.

I still had a decent time as a fan of the genre, so a thumbs up overall.
