Evaluation

Cavity Busters launched on March 18, 2022 and has received a steady stream of updates from its solo developer (SpaceMyFriend) over the years — adding new characters, upgrades, game modes, boss rush, trading cards, synergies, and balance improvements. The most recent substantial update shipped on April 14, 2025. The clearest signal about where things stand comes from a January 10, 2025 update post (NEWS-5), where the developer wrote: "Well is this the LAST update for Cavity Busters!? Who knows. It is for now... I'm working on my new game, Gum Flesh, and I need to get going on that." This framing strongly suggests the developer considers their active work on Cavity Busters to be winding down in favor of a new project. The subsequent updates in March and April 2025 appear to be the follow-through on the developer's own caveat ("besides the 900 updates I'll do to fix whatever this update broke"), delivering the 3-year anniversary content drop and a crash-save fix respectively. Since April 14, 2025, the only developer communication has been a May 9, 2026 post about merchandise — not game content. No future content for Cavity Busters has been announced, no unreleased DLC exists in the store, and the developer has redirected their focus to Gum Flesh. The game appears to have reached its natural endpoint as a complete, finished product.
Evidence
Developer states 'Well is this the LAST update for Cavity Busters!? Who knows. It is for now.' and explicitly says they are shifting focus to their new game, Gum Flesh.

Balance mode update shipped. Developer notes: 'I really gotta get back to working on Gum Flesh but I'll be around to fix bugs and probably do some more balancing' — indicating maintenance-only intent going forward.

About this game

Take control of Gummy The Soft, whose fall from The Great Gob was far and hard. Chomp your way through tough as teeth enemies and face the dreaded Pearly Knights, a true test of your enam-mettle. Collect upgrades AND diseases to enhance your agility and control over your one and only tooth. Brush and floss daily.

  • 317 upgrades to aid or hinder your run. Take a diseased upgrade and risk being able to cure the disease to keep only the positive effects

  • 10 playable characters all with unique abilities

  • Boss fights with multiple phases and attacks to keep you on your gums

  • Hundreds of handcrafted rooms and a new body to explore every time you die

  • Challenging rewarding skill based combat. No permanent stat upgrades

  • Slow motion

  • Accessibility options

  • So much bodily fluid

  • More teeth puns then you can shake a tooth brush at

  • More fun then going to the dentist

  • Cheaper too

  • ....unless you have insurance

  • or you know someone

Use the agility and stickiness of your little gummy to run on walls to escape bullet hells. Jump high into the air to get a better view or to dodge an impossible amount of bullets. While your in the air, why not take the time to reflect on your life. The purchase you made....WAIT! That enemy is stunned! JUMP ON IT!!! As a kid, did you ever try to re-insert your baby tooth back into its gummy cavity? No? Well now's your chance! Shoot your tooth and suck back! Time it just right to inflict extra damage.

Diseases

Contract diseases as you play. Diseases are powerful but come at a price. Do you risk the poison of diarrhea for the speed and urgency it creates in you? Leave the disease behind, and the body will consume the disease increasing the difficulty. Take entamaphobia to give all doorways a powerful laser. However, doors now cause damage by going through them. There's a creature that can administer a cure. But where and when you find him is unknown.

Bosses

The Pearly Knights wont go down without a fight. Face bosses that will fight tooth and tooth to guard their... little rectangle room... But they love it and it's theirs so beware!

Do you hate rogue-lites or need a more chill experience? There's options to make the game more forgiving! Want to start the game with a bunch of health? Want to give yourself a little power boost? There's more subtle options that no one will notice if you use. This wont block off content though. You play how you want.

A note to potential buyers

At first glance, Cavity Busters looks like your run of the mill roguelite. However the game has some unique mechanics. If you'd like something new in the genre, I believe you'll have a deep, rewarding experience!
