I finally solved No More Heroes! Hurray for me. (taking a break and coming back to it later really does work). Extra skills can really throw you off. That's what I tried to do on some of my recent levels and it didn't work out so well for me.
Anyway I attached a folder of my levels; some new, some fixes.
I adjusted Tinker Tailor Soldier Lix slightly to make it work better. I was able to solve it my way as it was so Idk why no one else could. But in any case both solutions (mine and Proxima's) work well now & I guess it's an argument of which is better or harder. As for your backroute, we'll just have to wait for an update to fix that digger/miner trick. I could put steel in the beginning, but I'm not sure I want to take Proxima's solution away as it was good.
Now I guess I have to put in a time limit to take away all the backroutes to Division of labor, as there's quite a bit now. I Also took away the climber which I don't even understand why I put it in to begin with, I shouln't have.
Then I have a hard version (not too hard) of one of IS easy levels.
The third is a simple misdirection level of ~tricky/fun difficulty. I'm not sure about this one I just threw it in case.
Lixes in Arms is a remake a from MazuLems.
As for Four Lix and a Funeral, at this point I think I will simply go back to one of my earlier designs. Which ever one you think is the best.
