Developer's description
Summer Beach is a spiritual successor to Sexy Beach, an adult 3D dating simulation game.
In the summer after high school graduation,
with no clear plans for the future, you arrive at the seaside town of Minamihama Port, far from the mainland.
Expecting to coast through the summer working part-time at your aunt’s small drink stand,
you’re immediately greeted by the "Minamihama Port welcome": your luggage gets stolen,
your rent is a scam, and your daily wage is unfairly low.
Just when you think your life is about to become a daily grind in the "garbage disposal group," you realize—
This is exactly where your fate begins to change.

almost unplayable due to bugs, also idk why it performs like wuthering waves on ULTRA MAX SETTINGS due to occasional stutters and lag, I had to double check if it's unreal engine or not lmao gameplay: you mix and serve…
Red2462026-02-07★★★★★
Yet another 3d, 5fps slop amazing, not to mention that the game version is marked 1.09 and if thats 1.09 then i am assuming that 0.1 was just a black sreen. Also not sure if mc suposed to be transparent…
eljohn142026-02-07★★★★★
the game is good, but still a lot of bugs, like sometimes some UI stay on your screen, some animations are buggy like hug and kiss and the rock paper scissor after playing that minigame the girl still follows you…
