I like the game, I really do... but I just don't like that I can't save ~anything~ for more than 12 hours or so. I got it to save once, but today my progress is reset again. I don't play games on NinjaKiwi, I play them on Kongregate. It's too much hassle for me to unlock everything over and over if I want to play over the course of several days or weeks...
I find this a pretty good game overall, however the heavy speed blurring gives me a motion sickness. Running the fastest car on the tracks (I skipped buying every car in between, as I often do when I can in racing games) makes it near impossible for me to race due to both the blurring and the motion sickness that comes from it. It seems well put together and all, no complaints on how it actually handles and I like it in general, but I cannot play this for more than about 3 minutes without feeling sick. If the blurring wasn't so bad, it might not have such an adverse affect.
