I am new here but i will fund some milestone, so you can trust me and work with peace of mind!
Our budget is extremely low on this as we lost double of this budget with previous developer.
He is not willing to work with us anymore and we have no more contacts with him, only we have .apk, check here > https://www.dropbox.com/s/gddhzidyzmrsoz0/RaceGame-10-18-2015.apk?oref=e&n=333491499
We can provide some designs/Car models for the game but no tracks (as we used our own designer)
Not may be 100% but all UI, so whatever our designer did, she will send us the files
But unfortunately we don't have the code as i mentioned.
Also app has :
etc social sharing features
Please respect budget, if you can't, don't waste your time.
