If you like Bunny Girls and Metroidvanias, be sure to check out Bunny Must Die! on steam. It's pretty good, and a real inspiration for something like Rabi-Rabi. It even has a unlockable second character with her own abilties, storyline, and new bosses, so it's essentially 2 games in one
Zeno Clash. Grotesque but amazing art style (normally I hate grotesque things) Fun story, intruiging, what is this secret father mother hides?! Get to the final fight. Can. Not. Do It. Ah well, youtube the final cut scene. Wait, that's it? That's the big reveal? .... That's not shocking at all.
It's been about a year or two since I last read this webcomic.
It kinda warms my heart to see the photonote traditions of "MINE", "POW! HAHA" and the like are still around.
I just realized that I need to add fanservice for Jo to check a game. Well, this is Umihara Kawase official art! http://gematsu.com/2015/02/sayonara-umihara-kawase-chirari-japanese-box-art-screenshots
Rabi-Ribi is a metroidvania. Not only you need to grind a little, you need to explore places to find power ups and badges, or maybe even easier bosses. The game is ridiculously big.
