Finally got around to fixing up my R1 and R2, as well as finish an R3!
See the update topic for the new level and the music file for it 
For R3, it's another attempt at my hand of making a 1-of-everything level, and I think you all can guess what official level it's based on from the title. I simply took things further and created a solution that's only a bit harder. Honestly, this took a lot of tweaking and thinking in order to make sure it all can be done within the 1 minute time limit. In earlier versions, the intended solution was too slow by about 15 seconds!
Also with figuring out how to make do with the 10 skill type limit. There were some things I wanted to include in the solution but I couldn't due to the limit
I'm not advocating to expand it any further, 10 skill types max for a level is already more than enough! If you need more, there's always pre-assigned skills, but that's not allowed for this ruleset. However, I persevered and finally managed to make it work
Sad to say that I couldn't really think of anything better for this ruleset. I just kept having my mind stuck on this type of level from L1 in the Mayhem rank that I wanted to make.
R1 - Armani and Icho already have the intended solution for my R1, but based on the feedback from Icho's LP video, I decided to release an update that should ease the execution in the bottom left area. In this case, it's not to fix a backroute, and I already told him that he made that area more complicated than it needs to be, as there are multiple stacker positions that still work. The position he placed it on the wooden staircase is not the only one that works. Needless to say, it was self-inflicted on his end
So, for V7 I just added a small sloping terrain on the wooden staircase. This very small and minor change is enough to break all replays, including mine, but it's just tweaking a few skill assignments and it should be good again. Not only that, it's also to enforce a trick I intended in that area better. In the previous version, it was possible to get on top of the stack without the trick I intended. In the updated version, it shouldn't be possible anymore without it, but feel free to prove me wrong.
@Simon - I took your feedback into consideration about the timer, and sorry to say it, but it will remain in place for the level. It's not to frustrate players at all (it's possible to finish upwards of around 10 seconds or so) but rather to stop any unwanted waiting you and Armani did in the bottom left area and to block off a backroute that would be possible without it, and not even pickups will stop the backroute here without the timer. Not all of us hate time limits, and I happen to be a huge fan of them, being a math person myself, and pretty much any levels of mine that do have one are pretty much for backroute prevention. I still have a handful of levels without time limits, so you might want to look at those if you're interested
R2 - Again, Armani and Icho already have the intended solution, but there was a glaring backroute that eric revealed. For V7, I covered most of the thin pole near the upper far right area with steel.
Here, I want to thank Icho for telling me his method of how he achieved thin steel pieces on Hurricane 13 of Pimolems. It really came in handy here!
Once again, this change broke all replays, including mine, but to fix it here all you just need to do is tweak a few skill assignments on the far right side.
