Jeez, everybody is posting so quickly on everything lately... I can't keep up
If you want to do it, sure! by all means.
I really don't have a lot of time atm, but I could do a few things, you can ask me about whatever. I do remember backrouting a few of Pieuw's levels, I'll see if I can find old replays or just remember the levels.
I'm glad Pieuw agreed. Has he said anything about what to do with levels that don't work in part or whole?
Some levels may just need a quick and simple fix that wouldn't even be very noticable; while others may require more serious changes. Some levels might still be possible but the exact solution may not be at all possible.
Some of the major issues I can think of off the top of my head:
-timed bombers
-the timer of Lemmini is tighter
-miner's don't turn on steel
-splatters can explode
-direct drop does not work
-while I don't think Pieuw or Dodochacalo ever did this, Gronkling definitely has; look out for entrances with terrain behind them to turn the lemmings.
