Pretty cool game. I think the level layout for the city was pretty neat. As said in other reviews it was hard to tell where to go. I played the tower level and fell through water maybe? I kept falling for what felt like a minute and then I got a page with a large restart button that didn't work. I couldn't play the tutorial either, the button didn't work. Other than not knowing where to go I would say if the camera was farther away from the tank/car it would have been much easier to control. Anyway, well done!
I just played it a few more times to make sure I would report it and finished the level. The other times I played it I didn't have enough speed to make the first jump, so I ended up falling into the water and getting to this Restart button which didn't work. The last to tries the button worked, so I'm not sure what's going on there.
However, I did again try the tutorial and nothing on that screen does anything that I can tell:
I hope that helps!
OK, just tried the tutorial again and found the space button moves the tutorial along. since I had just clicked with the mouse on the buttons I thought I was supposed to click and it did nothing so I just assumed it wasn't finished. That being said I bumped your score, however I would recommend adding a comment to tell the player which button to use to continue with the tutorial. Thanks!
