Hakoniwa Explorer Plus
The gameplay is roughly on par with something that might have been on a PSP from the 2000s, but what keeps the experience from getting stale is the sense of humor, and the way how the game reacts to player actions. Just be sure to keep your hands off people’s bathing suit areas, otherwise you’re going to have a bad time.
Overall, I’d say Hakoniwa Explorer Plus is a quirky little adventure game with a lot of interesting gags, a solid base mechanic, although it may need some slight tweaking, and enough big boobed/butted large bosses to easily identify the improbably female boss cast. While there are a lot of aspects that need a little touching up, such as the supped speedy rate at which your weapons deteriorate, the gags, simple gameplay, and school swimsuits will probably have you coming back for more.
