Hi, I'm an expert Unity3D developer with more than 5 years of experience. Worked in augmented and virtual reality, casual games for Android, iOS, web and pc platforms, 360 image viewers, and currently
Strong skills in OOP programming, design patterns, reactive programming, dependency injection, version control system, and other best practices in software development.
I've tried your game and it's totally possible to remake it in Unity3D, and even we could consider improve it (multilanguage, UX, graphic design)
In order to start working on it I would need the texts and graphics included in the flash version, and the web service for posting/retrieving the score
Please feel free to write me or ask me any doubt.
PD: Good game! I liked it :D
