Cumona Beach is a Ren'Py visual novel by Dunderdeuce, presented with animated 3DCG visuals and mobile-friendly releases. You play the main character, a recent graduate returning to the seaside town of Cumona Beach to see old childhood friends. His main goal is to help mend a strained relationship between a mother and daughter, who are former neighbors, while staying in their home during the visit. The story uses player choices to shape interactions and adult scenes.
The current build is v0.11, released on May 15, 2025, and development is ongoing. It is available for Windows, Linux, Mac, and Android in English, with no censorship. The latest changelog entry, v0.10, improved older interiors and exteriors, introduced three new locations, expanded choice-driven adult content, and adjusted Nicole’s appearance. Earlier entries mention updated character materials, new scenes, and fixes related to Nicole.
Developer's description
MC has just finished his education and is now on a trip back to Cumona Beach, to visit old childhood friends.
But most important, he’s on a mission to try and repair a damaged relationship between a Daughter and Mother,
who happens to be his old neighbors. Luckily he gets to stay at their house during his visit.
v0.10
Old interiors/exteriors have been improved and three new ones are introduced here in 0.10.
More panties, feet, hair, and general sexual content depending on player choices.
Changes:
Nicole has received a slightly bigger butt.
v0.9
Erica (The receptionist) has had her eyes changed mid-through the update, hopefully it’s not too jarring.
All characters in this update have had their materials/skin adjusted for Blender 4.0, from 3.6. The first half of day one lacks this adjustment and may seem a little off.
v0.8
Two more days containing both butts and feet (+more).
4 animations.
Changes:
Emma has had her face very slightly altered, making her cheeks less chubby.
v0.7 Part2
4 animations.
Fixed some issues regarding Nicole and her spanking path (dating back to v0.6). Players could advance with her without meeting the intended requirements. I would recommend people who never spanked her but played out the sauna scene to rewind back to before that scene. Removed one choice from v0.6’s content, and made the outcome dependent on a previous choice instead. (It was regarding a joke by the xxx store) No one should be affected going forward but some might have missed a tiny bit of dialogue from back then.
v0.7 Part1
One more day. (Day two will be in the 2nd part.)
2nd 2 animations. New haircut for the MC and Erica (the girl in the lobby). The previous jacuzzi scene has been partly re-rendered, no change in conversations/outcome.
v0.6
Two more days back at the house.
2 animations.
Important: Players with old saves will be prompted to confirm an old choice from version 0.4. This will happen before a certain scene on the second day of 0.6. You will be reminded of what it concerns when the time comes. Starting over from the beginning is not needed.
-NOTE unaffected saves won’t see this in-game.
v0.5
Two more days with a very small hint of the third.
3 animations.
Improved the look of Hanna (Molly’s best friend). Some issues with her eyes forced a slight change of her appearance in 0.4, which is now improved upon in v0.5.
At least 4 new custom interiors/exteriors, plus some tweaks to old ones.
v0.4
5 animations.
Final(?) twister ice cream scene.
First scene by the pool area.
At least 3 new custom-made interiors/exteriors, plus some tweaks to old ones.
Changed the names of some old images.
New dialogue box (still the old one for android).
v0.3
Two more playable days and four more characters are introduced in this version.
Fixes: Some small inconsistencies in 0.1 have been fixed, as well as a handful of minor bugs from both 0.1 and 0.2. (Thanks for reporting some of these bugs)
Important:
Some players with old saves (depending on choices)
might be prompted to confirm an old choice from version 0.2. This will happen within the start of 0.3 and you can continue as normal after this.
-NOTE unaffected players won’t see this in-game.
V0.2 consists of two playable days, in addition to what previously existed. One where he’s introduced to his new workplace and one purely by the house.
The first actual workday will come in the next update.
Changes: Alex’s skin textures have sadly been changed due to issues with very noticeable texture seams.

I gotta say, if this game had more taboo dialogues would be a perfect 10/10, but the taboo dialogues are not present, just the ocasional mom and sister mention in the game but not actually deepen in the taboo if…
