Reached the exit in 619. Not sure if I'll keep trying to optimize but it's a lot of fun to figure out how to keep everything alive! Great job porting this, you used some nice mechanisms to make it work :D
Nice manipulation/storage on the right side! Great to see your levels :) I think I would personally prefer it with fewer blocks/holes - feels like the ones in the middle don't add as much puzzle-wise as the ones on the ends, if that makes sense.
Very fun to puzzle through! Also very scary. 464 so far.
EDIT: Starting to carve down my path. Still lots of fun! What a monstrosity of a 10x10 with one hole.
