Develop game now

I want to build a project very similar to the one below: [login to view URL] but i want it to be done in 3d road and 3d characters, with the below comments: 2- the characters should all be in 3d (I can send u links for the drawings) 3- all characters can be bought by the coins that we collect through the game except for 2 of them that can be unlocked by watching video ads 4- the roads in some cases look like 2d, they should look more 3d 5- the colors are sometimes not matching (game should change colors each 10 seconds, the set of colors can be provided in psd) 6- the 2 lines on the edges of the road are sometimes not correct, and should be colored as the psd
