About

Delicious! Nutritious! MALICIOUS!
Rebbecca Valentine is a raccoon with quite the appetite. This game takes place in the corrupt, poorly run company that is her stomach. You play as a lowly worker cell, and perform the dangerous duty of breaking up the food Rebbecca eats with your acid blaster. Keep up with Rebbecca's eating habits, as this is supposed to be an iron stomach, and your Boss expects results--and she's not gonna be happy if you fail and make Rebbecca sick!

Hunger Pangs!! Bust a Gut, Bros!
GutBuster is a classic arcade-style shooter, with hand-drawn animations and satirical comedy about corporate greed, the digestive system, and erotic gluttony. Controls are simple: just run, while the gun shoots upwards automatically! Run and use your dodge-roll ability to avoid the food targets as you blast, so you don't get crushed! This is a challenging, yet casual game where you can continue as many times as you want. Accessibility options are available if you want to make it easier, or just want to see the story.

It's 'Zyme Time!
Bust open Enzymes to acquire one of five different Power-Ups to help you fight harder and get bonuses. Bust'em up quickly with the Bile Blaster! Use Tri-Glycerides to spread out your shot! Use the power of thirst to slow down targets with Osmosis! Protect yourself and counterattack with the spiny Cell Wall! Or make yourself rich with the outpouring of lipids from a Hormone Spike!

Fatten Your Wallet, Too!
Collect lipids, then spend them at the shop to upgrade your blaster, make power-ups last longer, increase the appearance of lipids and enzymes, or even divide yourself for extra lives, and increase your odds of survival in this escalating challenge through 40 fattening levels, as the difficulty increases along with Rebbecca's weight!
Help Rebbecca to overcome any eating challenge, and don't give her indigestion!

Five different power-ups to help win the fight!
Robust upgrade system to increase your powers!

I will never admit how many times i died 100% this thing.
Fat goodness fat good time. Buster bros gameplay good must and lots of food to break down. What more can one ask for other then another game to keep going please.
I recommend playing this game if you like arcade style games. And if you're a fan of RoyalJellySandwich, I would DEFINITELY play this game. Personally, my favorite chapter is the burger stages. Cuz Rebecca is at a stage of fat I personally love. I look forward to whatever game RJS makes next.

this game is total ♥♥♥♥♥♥♥ i ♥♥♥♥♥♥ hated 100%ng this ♥♥♥♥ would recommend
Been playing on the steam deck. Game is pretty great up until stage 30 or so. Then it starts randomly crashing when you take damage. Kinda making it hard to enjoy. All that aside it really is great. The fetish element is also hard to pay attention to cause the game element is stressful and demands your entire attention. I 100% recommend this for folks who want an arcade style game.
An easy to learn hard to master Arcade Hit that wouldn't look out of place on the Sega Genesis!
A bit tough, but it is a fun game to play.
This review is aimed squarely at the game side of this project. As the thematic elements are squarely up to a specific person taste. Though I will say I found each cutscene charming in a "oh you" eye rolling type of way. I wana say this game is a good example of how tweaking a single element can really revitalize a gameplay concept. I tracked down the original buster brothers games to compare and its night and day what the focus is for both. This game is more about playing chicken with each bubble and gambling you’ll have enough time and space to slide out of the way of the bubble’s above and around you. While the original BB games were more focused on spacing, controlling when and how you busted the available bubbles. I played GB first and was a bit frustrated at points wishes I at least had the ability to pause firing for a moment or so. But that would actually take away from the frantic strategy GB has.
Great game, probably the only one in this fetish category that had me play more for the gameplay than the actual "rewards". RJS managed to do what most creators in this niche fail to do and that's balancing it being a game and being kink stuff. GutBuster feels more like a game with fetish content than fetish content with gameplay. I liked the cutscenes, even the death scenes got a chuckle out of me. Great time killer and simple to open and play. All I have left to say is... Rebbecca dating sim when?
Classic arcade-style rogue-lite gameplay paired with animations of big girls getting bigger. What else do you want
