Grimm Glitter is a self-published eroge Rampage-like Beat 'em Up published on June 4th 2020 by the group known as Grimm Glitter Development Team, a cooperation of notable Giantess focused artists.
The story begins with Ordinary High-School Student Aoi Hyuga finding a mysterious black cat, who leads her into a mysterious world that looks suspiciously like Wonderland from Alice's Adventures in Wonderland. She quickly finds herself in trouble when a giant machine sets its sights on her and needs to eat the famous cake that makes her grow into a towering 70ft version of herself. She then stumbles upon a girl who's just as huge as she is named Alice who quickly befriends Aoi after an unfortunate bout spurned on from a misunderstanding. Aoi starts putting the pieces together that she's actually been transported to a storybook world that closely resembles the very novel she imagined. The two then go on a journey to discover more about the world, and the mysterious machines that accosted Aoi on her initial visit. This includes heading into other stories and meeting a genderbent Gulliver from Gulliver's Travels.
While a niche game targeting a specific audience (Macrophiliacs) it has nevertheless garnered a cult following. Enough so that a creator-approved Fan Sequel is in development using the Unity engine by a user named Snowdrop. Titled Glitter Invitation, the game takes place some time after Grimm Glitter and sees the cast inviting a certain boy to their now daily Giantess shenanigans. While Grimm Glitter has yet to be translated, Glitter Invitation actually is implementing an English language option alongside its usual updates.
This game provides examples of:
- Attack of the 50-Foot Whatever: You control girls larger than buildings and fight giant mechas and creatures of similar size in order to reach the next goal point. The size shenanigans get even crazier with certain moves, scenes and with the Super Mode.
- Big Bad Friend: The main villain turns out to be Aoi's best friend Kaori, who created the storybook world with the assistance of the fox spirit Mitama and intends to move away into the real world with her now enormous body to become a very real Demon Lord. Aoi is able to break through her shell however, and ends up redeeming her, creating the storybook Grimm Glitter as a way of preserving Alice and Gulliver, as well as their adventures and time spent together.
- Fighter, Mage, Thief: Aoi is a brawler who fights foes directly and has the best durability, thus the fighter. Alice is frail but has a boatload of MP that she uses for powerful abilities that cover a wide range, thus the mage. Gulliver attacks from a distance and uses indirect attacks that trap or catch foes off guard, thus the thief.
- Gender Flip: Gulliver has been gender bent in this game, which confuses Aoi as she's familiar with the actual Gulliver's Travels where Gulliver is a man. This isn't a coincidence, since the storybook world is at Kaori's command she has the ability to change details of stories to match her preferences.
- Our Giants Are Bigger: While the cast spends a majority of the game being the biggest things in any nearby vicinity, once they travel to Brobdingnag they find themselves hopelessly outsized and need to seek cover from naturally enormous women.
- Giant Foot of Stomping: Every character has some variant of this as an attack, though Aoi and Gulliver will need an exorbitant amount of MP to use it.
- H-Game: Actually pretty downplayed for a majority of the game. For most of the main story the most risqué thing you'll see are a couple of Panty Shots. (Unless you lose to Alice) It isn't until the Postgame that the game starts revealing its eroge nature and the girls start doing some... interesting things on a country-wide scale.
- Have a Nice Death: A few specific bosses have an extra cutscene if you lose against them. (usually at the expense of poor Aoi) Alice's is probably the most extreme example despite being the first occasion, as she grows even huger and ...toys with Aoi to put it nicely.
- Mouse World: Brobdingnag, full-stop. The girls are hopelessly smaller than the very grass around them and are in constant threat of being squashed underfoot by passersby girls. Most of the enemies reflect this, being snails and plants that don't actually look out of place with the size of the party.
- Secret Character: Kaori is unlocked upon completion of the main story, then Mitama is unlocked upon the completion of the Knowledge Country’s postgame story.
- Super Mode: Upon tapping the Giga Mode key the character you're controlling will triple in size, becoming an unstoppable juggernaut for as long as the special meter lasts.
