Underwater RPG

Underwater RPG is an underwater-themed browser idle RPG by Thanapat Chaumthong. Its opening loop is built around fighting, clearing stages and earning rewards before moving on. Guest access offers a starting point for players who want to try a browser RPG without signing in.

Combat and progression

The combat interface displays AUTO and MANUAL options. A limited early-game test observed damage being dealt and stage one being cleared, followed by rewards and the unlock for stage two. Fighting to clear a stage and progress to the next is therefore the part of the loop directly verified.

How to get started

1. Open the official game page and choose guest access to try it without signing in.

2. Enter the opening combat and watch the damage and the AUTO/MANUAL options on screen.

3. After clearing a stage, check the rewards and newly unlocked stage before continuing.

Creator information and testing scope

In Thanapat Chaumthong’s introduction post, the creator describes the game as deployed to production, with guest access that requires no login, and invites feedback from testers.

GameSlash performed a limited hands-on test on 21 October 2026, observing combat, stage-one completion, rewards and the stage-two unlock. This is not certification that every system or stage works correctly. Long-term play and save persistence after reopening the game remain unverified.
