Alright, points to ponder. Here's some background information for you.
I run a PC, Intel Celeron, Windows 7, 2.5 GB RAM. I am a Supporter on Newgrounds, meaning the ONLY Flash running on this entire page is this game (ads have been disabled). I will mark headers as I go along.
UI
The UI looked like something from really early PS2, or really late PS1. I don't really know if there was anything particularly special about the UI to add or take away any marks... it was clean, but it just wasn't my taste.
SOUND
Practically non-existent. My comments on this in relation to the game in general will be later in this review. I emphasise: solid sound is key to a good game, and this really didn't give me any enthusiasm to play.
GRAPHICS
You stuffed a 3D game into a Flash, which is impressive. The graphics are, once again, between late PS1 and early PS2, which is probably understandable for a Flash of this size. However, considering I DO NOT have any other Flash stuff on except for this game....... the severe lagging here is inexcusable. Loading times are slow, selection times are slow, even the time taken for tracks to show up is immensely long.
CONTENT
There seems to be a lot of effort thrown into cars, tracks, characters, even side functions, which is great! My only pickle is, with cars, tracks and characters, is there no means to show, say, the acceleration, speed, handling and difficulty for each? Is everything going to be the same?
OVERALL COMMENTS
Now I know a humungous amount of effort has been put into this game, but the key points of any game, to any player, are 1) functionality, 2) atmosphere. And if these two don't work out well, how can it be a great playing experience?
There are perhaps many of us who could try playing over on Facebook, but there are some of us, who for space constraints and loading issues, resolve to playing on Newgrounds (especially if we are Supporters rather than ordinary members). If it doesn't work on the site with lower bitspace -- Newgrounds in this case -- how are we to trust that it'll work on Facebook?
Although credit is due for your hard work towards this game, this is one thing where I must honestly say, downgrading the graphics for functionality's sake would've worked really, REALLY well here. Or, if you cannot compromise on the graphics, then take whatever time you need to make sure the functionality and atmosphere side can be enjoyed across all sites. Because at this moment -- and I trust you can make it better in future -- it seems like you tried to make a really flashy thing, but it's fallen flat on its foundations.
This is one thing for which I cannot honestly give the rating you'd expect.
3/5.
