Yes, I actually liked that level (but I hated that ONE tree XD...). When I figured out what I supposed to do, I thought it was still impossible to grab all the keys alive. Most of my levels are focused more on skill, but I wanted to make more logical ones like that one, and that was difficult than I first thought.
Well then, I've made a few tut levels like I said I would. They should be able to help you with my levels. I'll explain the methods.

Lot of warp forest players should know this technique. Spiders will be briefly stunned the first time when one is hit from enemy fire or your power missile. Also during that time, the creature won't kill you (and it's possible to drive through it alive, but that's not in this tut).

My Challenge 2 already brought this up, but this is a tut version. This technique is all about grabbing an item right b4 the spider devours it, and live to tell the tale. The starting point of this level demonstrates what the motion used is kind of like, but you must be more closer to the spidey while one side of the car is barely above the object, and the turn must be earlier enough to grab the object and cheat death at the same time. This can be done from any direction.
Stun_Crossing=eeyee1111y1111g1ee1e1eeeeeeege1 1111gee1eeg1111ee1yee1e11eegege1e11ee1egeded1 ee1egeye11ee1egeeey1ee1ygeye11ee1egede11eegeg e1e11ee1e11111gee12
Much like stunning spiders, but this time you're doing it to cross the path so that the spider doesn't move. You'll have to make use of the 'd' button most of the time. All you have to do is to turn slightly so that you can still hit the spider and when you press 'd', you will face the direction you want to go, but be close to the tile adjacent to it. For spiders that are pretty far, cross just when the power missile hits them. The closest ones are easier to do while the farther ones take more practice.
I hope I explained each technique well and I hope the tuts helped you :) . I'll post more levels later, cuz they're humorous (and in my opinion, creative)! You'll see why soon...
