Crane's R2 resolved. Admittedly, I already saw Icho's video on the solution after I had backrouted it when I cheesed it with the way I used the miner from several weeks ago, so I already knew what was intended just from that. To be fair, I wasn't sure if Crane was going to fix my backroute, as it was quite some time before he did. In any case, there are two solutions attached, one for each of the talismans. I just barely got the time attack one, as according to the record time on the post-results screen I got it with only .06 seconds to spare despite the timer showing 0:50 itself in level.
I also finally got around to recording the video on the intended solutions to my own contest levels
edit: Removed the link and reposted in my most recent post a few posts below so that the links for this and the other video are in the same post together.
Finally, before the end of the playing phase and the start of the voting phase, I have attached the solutions to my own levels in case anyone is curious about what I intended for them. There are two solutions for my R2, although really there are multiple ways to do the jumping in the level, so these aren't the only way to get it solved. However, the intended route and all other skill assignments besides the jumpers in the end should be the same.
