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.
- Genre
- Merge tower defense
- Core loop
- Buy, merge, upgrade, survive the wave, repeat
- Platform
- Browser, built for phones and desktop
- Built with
- Phaser 3, TypeScript, Vite
- 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.
Build
Ship the next mechanic or fix in small, playable steps.
Test
Hand builds to outside testers and watch real runs.
Measure
Read telemetry and run bot simulations on waves, upgrades and outcomes.
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.
