I am amazed.
Words cannot describe how I feel towards this game. It's graphics are amazing (I love that mode7 feel, I feel like I'm playing an old 16 bit racing game :D), and the gameplay is entertaining too. You even through a story (I don't even know how you managed) ni there that was actually kind of interesting.
The whole concept of this game is near perfect. I mean, everything in this game was cleaned and polished to look astounding to people playing it. This is also the first time I've seen a mode7 game on NG. The fact that you did all this in Adobe Flash kinda scares me. The gameplay is also very close to amazing and wowing NG users.
However, I don't actually get the feeling I'm driving a car. The whole map feels like it's rotating around the vehicle rather than the vehicle turning on the map (This cannot really be helped, though). The game itself was also rather challenging to play, mainly because it required a bit of skill to get the hang of playing it.
Besides those issues, though, this game is very entertaining, and people will keep coming back to play it. I can't get over the fact that you made all this in Adobe Flash... You must be a god, that's it...
