not a bad start and a pretty new an interesting idea, however there's many flaws, the game has no skill level at all you can beat everyone with as simple as 10 clicks, and the upgrades become useless because they don't really do anything.
A few ways you could fix this is make it so it requires a certain amount of clicks to beat each opponent depending on the level you are, upgrades could increase the amount of time you have to click and if you know how to code it how many clicks you can get per click, for example: 1 click could = 5 clicks.
lastly the models are nice however its really random with each girl you race, since daisy is growing her opponents should get bigger as she levels up making the smaller girls at lower levels and the biggest girls like the red head and blonde girl at the highest levels
