Welcome Kinhell
Nice to see a new player joining. 808 aint too bad. Basicaly i see 2 ways to solving this.
You make a construction where the metal plate stays about the same place and the dillo rolls to the right. This is expensive because you have to build something to balance both the dillo and the heavy plate on the right side. You'll probably need something to temporarily make the right side heavy enough for the dillo to actualy roll that way.
The other option is to make a contraption that flips the plate over to de left and the dillo under to the right so the plate will act as contraweight for the dillo. This should be the cheaper solution.
The second option is what i chose, but i also sent in the first option scoring 896.
The endtime is 1800 gmt. The gmt time link is in the topicstart. At this point you have a little less than 4 hours to send in your solution, so succes in tweaking it a bit more.
ps i've tweaked my own a bit more as well
