another minor update:

- fixed the bug in tutorial mode. due to an oversight, the car speed was being reset to zero when you restart a part of the tutorial. now that doesn't happen anymore and the tutorial can actually be completed again

- reduced the difficulty of easy mode a little. I've seen a lot of complaints from new players (including some negative reviews) that the game is too hard. being a little hard is intentional but easy mode is supposed to give a more relaxed experience. the normal/hard difficulties remain the same

that's all, thanks!
