Not to be a total dickhead, but to be honest this level is really horrible. I can't find anything positive about it at all. Just a few general tips after looking at the level:
* First of all, that auto start thing sucks, there are very few players that likes these sort of things. Although in this lev it's possible to volt a bit and make the start faster than just not pressing anything, it's way too annoying.
* You shouldn't make new polygons for everything, but just add vertices to an existing one. For example that half circle in the ground could have been added to the ground polygon, same with the two bigger polygons towards the end as well. It kinda looks like you've just added polygons inside the starting polygon when you open a new level, instead of using that first existing polygon to create stuff from.
* Unless you have a very good reason to do so, don't use gravity. And certainly don't overuse it, like in this level.
* There is a part right after the start where your wheel kind of get stuck inside the "rail" part, this is usually a big no-no. Although you might get through on your computer, sometimes people change their vsync settings and they won't be able to get through, causing a big annoyance. When you make these rails, you should use an apple or something for guidance in the editor to check if the wheel can get inside without snagging on anything.
making a video of you playing the level doesnt make it any better, and you wasted alot of work, you could have just uploaded a replay, although finishing the level wasnt that hard...
And please take some of skintors advices and learn how to make a level before you upload it here.....
There's a lesson to be learned right there. No matter how intricate and awesome styles you may plan for your level, if it's not the fastest way people aren't going to use it.
Dont worry, i wont repeat the same mistake, because i had only planned to make 1 gravity level. Basicaly to experiment with the gravity. So yeah, no more gravity maps . And yes skint0r, thanks for the tips/advice .
