Browser games, built and tested with real players.

CodePulse Dev is an independent studio. We write the engine code, design the game and use an AI-assisted workflow to move faster. Our first game, Merge Sentinel, is playable right now.

Merge Sentinel

A merge tower defense where a robot guardian holds the core. Waves of aliens attack from every side of a 5×5 board. You buy defenders, merge two identical ones into a stronger unit and choose boost cards and upgrade branches that shape each run.

Between runs you spend crystals on permanent upgrades, robot skins and unit skins, then try to push one wave further. The robot fights too: tap an enemy to fire rockets, tap the robot to release its eye laser.

Status
Active development; release checks remain

This is the hosted test build, not a CrazyGames release. A previous build was submitted to CrazyGames and did not pass its quality review. Further development and release checks are in progress.

Closed playtest data

During closed testing, the hosted build automatically recorded gameplay telemetry. These figures are aggregates of the recorded telemetry and run logs for the six-day test sample.

  • External tester IDs16+
  • Recorded gameplay runs25+
  • Wave reached in the test logs142
  • Telemetry observation period6 days

This is a small closed sample used to guide development, not evidence of a scaled public audience. Tester IDs and raw logs are not published.

Build, test, measure, iterate

The public game repository has 97 commits and includes the living plan, product brief and release notes alongside the source.

  1. Build

    Ship the next mechanic or fix in small, playable steps.

  2. Test

    Hand builds to outside testers and watch real runs.

  3. Measure

    Read telemetry and run bot simulations on waves, upgrades and outcomes.

  4. Iterate

    Rebalance numbers, refactor, release the next build.

Where Claude Code fits

  • Gameplay implementation
  • Debugging
  • Refactoring
  • Iteration on features
  • Balancing and supporting workflow tasks

Claude Code is a tool in the workflow. The developer sets direction, makes the design decisions and reviews the result. The game was not generated autonomously.

The stack

A lean browser-game toolchain with no unnecessary layers.

Phaser

Rendering, input and scenes. Units, enemies and backgrounds are baked procedurally, with no sprite sheets.

TypeScript

Typed game logic across the whole codebase, safe to refactor.

Vite

Fast dev server and a compact production build.

Claude Code

AI-assisted implementation and debugging.

Roadmap

In progress

  • Continue game development and remaining release checks
  • Prepare a possible revised CrazyGames build; an earlier submission did not pass quality review

Planned

  • Android
  • Steam
  • Additional content and iterations

Planned items are intentions, not committed release dates.

Questions

What is CodePulse Dev?

An independent development studio building interactive software and games with an AI-assisted engineering workflow. Its first product is Merge Sentinel.

What is Merge Sentinel?

A browser tower defense game where you merge defenders into stronger ones, pick boost cards and upgrade branches, and hold a robot core against alien waves across four zones.

What technologies are used?

Phaser 3 for the game, TypeScript for the code and Vite for development and builds. Claude Code assists during development.

How is AI used during development?

Claude Code helps with gameplay implementation, debugging, refactoring, iteration and balancing-related workflows. It is a development tool. The project is directed and reviewed by a human developer.

How was the game tested?

The hosted test build automatically recorded telemetry during a closed playtest. The figures on this page are aggregates of the recorded telemetry and run logs from a six-day sample. Tester IDs and raw logs are not published.

Where can I play it?

The hosted test build is available at merge-defense-meruem.surge.sh. A previous CrazyGames submission did not pass quality review, and the game has not been publicly released there.
