This is such a hard level and has many of the qualities that I attribute with "Grandmaster" style levels. Several of the sections "compete" with each other for path superiority and they all boast several somewhat tough to find 2 or 4 step cuts that will leave you at completely optimal 297 or 299 paths. The final 295 is just a great mix of many of the competing paths brought together with the correct timing.
293 tries for my first solve ages ago and 75 on my second. Still a monster of a level.
Oups, that was your level, Flashback. I wondered why that one was in my unpublished levels so I decided to change it a little (a second version is coming). Maybe it's time to delete this :D
This level gave me quite some troubles. At first I couldn't figure out, what to do. Once, I got that, I didn't worry about how to store ''resource''. It is really painful, if you're two off in a level like this, and several times. And you KNOW, where you are losing steps, but you're not sure, how to stop it. But, that aside, I like the concept of the level.
