Solved it pretty quick because of playing the original first, but the 310 is definitely subtle. I like this version more than the original, the updated areas add more close possibilities to this layout.
Having just rebeaten "Murder by Numbers", I would say I agree with Manti and the last one is better due to similar reason.
The top center of the previous version indeed tricked me initially and I blocked myself.
The most difficult part for me was in common for both levels.
After replaying this I think my 312 review was a bit unfair (path was mostly the same between the two versions with some little changes and I thought this one was more obvious), so I bumped this up 3-> 4.5. This is still tricky but i like the other version slightly more because the top center section has a lot of block entanglement. I do think the two levels play similarly since the left and right are built the same so solving one does eat into the nuance of the other a bit.
Spectacular level! I had a lot of 4-offs and a 2-off, and it turns out I was missing an imo really subtle way to save 2 more. Indeed this is better than the other version (which wasn't bad, but this was extremely hard to spot).
Good level. Interesting. 45 tries, for me. Here, I was 6 off (on 312 route), for quite a while, then came to 2 off and in one try found the two, while at the other variation, I am still 6 off. EDIT: had quite some trouble to find the latest 2 cut (new record 310), but managed. :)
