(6-8-2023) First time reaching the exit = 384
After much time, can only do 314, can't see any more optimizations. Shall come back later.
Really appreciate the construction!
(31-7-2023) Can't reach the exit yet. Great design.
(4-8-2023) I was doing it quite well actually but I missed one critical move. Once I saw it and I reached the exit, I finished the level immediately like what Manti said.
