Yes, publishing is a standard part of our Android game and App development services, and we never consider it an add-on. We prepare the complete store listing: screenshots, descriptions, promo graphics, content rating questionnaire, and the data safety form Google now requires. In general, we are always aware of the changes Google introduces, and meet the new requirements as a part of the game development package.
We configure the release in Play Console, sign the build, and set up a staged rollout, so the game reaches a small percentage of users first. If there are mistakes or minor flaws, it's caught before it reaches a bigger audience.
If Google's review team pushes back on anything, we will change whatever needs to be changed. We can publish under your developer account or help you set one up, and either way you keep full ownership of the account, the listing, and the source code.
After the release, the team that was working on the game monitors crash reports and store reviews, so the first post-launch update is based on real data.
