As a long time hotwheels fan this game does it all. If you had an imagination as a kid this is EXACTLY how you imagined the cars would race. From the handling, collisions and speed. If you watched the cartoon series (hw35, acceleracers) You will absolutely love this game.
Now for the technical bit.
Pretty much bug free as far as gameplay goes.
This game has a really high skill gap as of right now but with most games targeted towards kids it will be decreased if the game gets popular enough(like fortnite). In order to control the fastest car in the game (if you've completed the game on the highest difficulty then you know what car it is) you have to be really good at the game(like really good). But thats the problem, you have to use this car in order to win the majority of the races on expert. It shouldn't be this way. Either that car needs to be nerfed or other cars need to be buffed to be competitive.
