fun!
overall you've done a great job of making this GTA game, and i can't believe this is only part one (i didn't finish it all, it was just too long! haha).
i really like how you utilized the 'pink marker and arrow' concept from the game, as it worked out very very well.
i enjoyed all of the different missions and such, but i stopped after playing the rugby game (the most entertaining thing i did, but a tad easy)
all in all, very fun and entertaining. hopefully with time you'll improve the graphics and sound quality a little bit, and then later on make the action scripting a bit more advanced to enforce friction (eg the car hitting a building, etc), and so on. very nice work :D
