Already very good concept; if you guys stick with it and work out some of the kinks this could be a great game.
On a side note, that garage looks oddly familiar :)
I'm actually kind of disappointed that you can't see the custom names for other peoples' monsters in PVP. Maybe have the "official" name in parentheses underneath the custom name?
I'm sorry, but the music going back to the menu after some of the missions just utterly ruined the mood for me. It's a little too happy/triumphant sounding.
I feel that I got something valuable out of this game.
IF I feel that I got something valuable out of a game, THEN I love it.
IF I love a game, THEN I demand a sequel.
THEREFORE, I DEMAND A SEQUEL!
Pretty fun game, but it just seems like too much work to try and get the top tier cars, especially with just three things to do. Maybe some kind of campaign/race mode against others or NPCs. Also, and this is more of a technical detail, the graphics auto adjusting itself was kind of annoying. I turned it down to boost the framerate, and then it turns itself back up. Just a suggestion.
