Hello,
I am a French engineer in Computer Science who lives in Sweden.
I have been working as a Freelancer for 6 months and I worked in various field of computer science before that (from Research in Pervasive computing to mobile application development at Orange).
I like your project and would be pleased to offer you my services.
In 4 days your project could be up and running and I am confident enough that these 4 days would also be enough to have a game that looks nice than the demo you shared and that would be mobile & tablet friendly for the same price.
Do you have any constrain for the back-end part? (no back end at all, PHP, NodeJS, Python...)
I would be glad to discuss these options with you.
Moreover, I have some ideas that could be interesting and that I would gladly share with you if you wish.
Best regards,
Leo
