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!

hello, my name is Targeted Audience. this game is very good in all aspects, no complaints, very fun, love the art and humor
fat girl hell yeah
100% recommended if you have a fat fetish and love super buster bros
An interesting spin on a long-forgotten style of game. The character and background designs were great, the writing is sometimes REALLY funny, and the upgrades system is much more in-depth than I was anticipating form this type of game. The comic-style cutscenes were charming, too. I kind of wish you'd keep your power-ups between lives if you lose a life in the middle of the duration of one, but that's a minor gripe. The soundtrack also wasn't my favorite, but it was alright. In contrast to the music, the sound effects and overall sound design were fantastic. Not to mention, the fact that it was all kept tonally and thematically consistent throughout the entire game shows a level of dedication you rarely see in games that only cost $5. Overall, 9/10, totally worth it. If you like this sort of thing, it's one of the best of its kind.
Really fun game, enjoyed the visuals and the gameplay. and I'd say its a solid game for 5 bucks
Ok, I played a good 12 minutes of this and...It's quite a lot of fun and a great hidden gem of a game to start 2025! the game play is challenging and fair and unique, the jokes are well made and utilized body functions to a great genius level degree, the artstyle is quite cute, and the, yeah im gonna say it, fetish aspect is well used here! Definitely a 9 out of 10! ^^
I'm gonna bust a gut
Underrated Gem! In all honesty I'm a big fan of Furry Games especially small projects like this. They're usually really creative regardless if the gameplay loop is boucey Space invaders. There's always some creative twist to someone's perspective that makes it worth playing. If you have any future projects I'd gladly support them as I can only see the quality going up from here.
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.
As of right now I just finished getting every achievement in the game. this was a very delightful shoot'em up, (or Digest'em up hehe) the levels were fun and never felt like they were too long.
