Having worked extensively in game development, specifically in Unity 3D, I believe I am an excellent fit for your project. From my past experiences, I've tackled multiple optimization challenges, which makes me confident that I can successfully increase your character count without compromising performance. One of the recent projects I undertook involved optimizing a similar game for the Android platform where I exceeded the client's expectations by improving the FPS from 25 to 60 while adding 100 more animated characters than originally planned.
Not only can I deliver results, but my dedication to projects is unwavering. Given that you require someone who can commit full time to the project for several weeks, it aligns perfectly with my current availability and enthusiasm to be a part of something special; your WW2 crowd game seems like an exciting venture to embark upon. Moreover, as a bonus skill, I have solid experience in AI implementation and multiplayer games, which might prove valuable for your project.
In conclusion, if you choose me, not only will you benefit from my technical expertise but also from my passion and commitment because when it comes to creating exceptional experiences across various platforms for gamers, sacrifices are worth making and new horizons are always welcome. So let's dive into this exciting venture together and make your WW2 Mobile game a massive success!
