I am proud of this level. Pretty complicated to reach the exit and basically none of it was broken despite minimal testing. Not really convinced 549 is optimal, but I found it surprisingly doable now that I am better at optimizing. I'll probably keep looking for more just in case it's possible for me to take the record back.
This level at first completely stumped me. I couldn't even figure how to touch the exit. I was trying all sorts of things, but wasn't trying correctly, so I gave up the right idea, at first. Later I just had to come back to it, lol.
I now have it at 559 and will keep looking. I think FlashBack did some magic, that I hope to find, too. :))
GREAT level!
