Thanks for the kind words, kaywhyn!
Oh, and I recorded myself playing these https://youtu.be/-A6phUtNrvo
My pleasure and thanks for playing my levels!
Thanks to you, some backroutes for both my R1 and R2 have been discovered. For R1, that's a very bad backroute. It's supposed to be far harder than that. That is, unless there are still some backroutes that still break the level. I suspect if the intended solution is enforced, it could possibly be the hardest level in the entire collection.
For R1, I added some steel, shifted a steel platform in the middle left area, shifted a fire trap, and replaced a trap with a different one. I'm not sure if this catches all backroutes, but well, let's see.
I realized that one for my R2, but I didn't think it would come up. Good find!
For V3 of my R2, added some OWAs. This should do the trick!
For my R3, watching you have an attempt at it is quite helpful for me, as I get to see how one might go about solving it, as well as see what kind of things could trip people up when doing so. I can see that in a way I unintentionally made the level harder than I thought I did, as honestly my R3 is completely meh since I couldn't really come up with anything good for it other than the trick at the beginning that I wanted to include in the solution. For example, you showed me how a lot of possibilities you have tried come up at least a skill short. Not to mention I threw in far more red herrings than I thought I did. All I have to say here is that all of your attempts are a bit far from the intended route. However, the hardest part is the very beginning of keeping everyone safe. Once you do figure out how, the rest will fall into place.
Again, I can't thank you enough for these replays to my levels and for playing them!
