I wanted to get above a minute, but I got a bit annoyed about a few things. The dash streak goes through the perimeter; you could just add, like, a boundary sprite on top of that to stop it. There needs to be a reset button. I think the timer should only start when you start moving. The sounds need some variety. The Zs on the thumbnail is different then the pickups. I'd like to give high marks because I like it, but because it is such a small game, half of the rating for audio would be to like have variety, and that goes with the other ratings.
I do like the Flash game vibe. I think you thought about picking up two Zs at the same time for the audio, which would be a good eye if you did. At first I was like, does this really follow the theme, but after thinking about it, it does. I think there is potential in bringing the game out of the Flash game vibe and adding different levels, items, and mechanics.
8/10, flippin got 59 instead of 60 on my third attempt, which means I SHALL NEVER GIVE MORE THAN 8 for you have doomed me. I'll come back someday....
