Very happy with the game! I'm happy that someone took the time to make a game dedicated to one of the greatest years in F1 history! The game runs very smoothly, and it's a very fun game to play if you get everything right. I would like some features that I was somewhat surprised to see not in the game otherwise:
Qualifying?
Possibly an adjustment of brake power (currently lifting off the gas basically brings your car to a dead stop, maybe make that adjustable)
Fixed hitboxes (the hitboxes currently are very weird in the way that sometimes the AI gets punted off and sometimes you get punted off, it can get very annoying when you're trying to get past an AI that is extremely slow)
Field of view adjustment? (the current field of view is VERY small, so you normally don't see the corner coming until it's too late, if we could zoom the game out, then that would make the game much more playable)
Practice mode where you can drive unlimited laps of the track, try different setups, and whatnot without any AI?
Possibly fuel consumption and for the super-hardcore fans, actual GP-length races (safety car periods maybe too?)?
Car damage that could force retirements?
If those things are added, this game would be rated 5 stars. Now... onto the positives...
The game itself is a LOT of fun to play. As I mentioned before, it's not a very forgiving game if you run aggressive setups, but those setups can pay off with the extra speed. It's also super satisfying to nail a particular set of corners flat-out and overtaking many AIs in the process. The intro sequence itself was done very well. All of the medals take a real damn effort to get, and that's also what makes the game so satisfying to play.
Overall, one of my top flash racing games, but only a couple of things to be added and it WILL be the top flash racing game I've played.
