Really unique design idea and very well implemented. Had a lot of fun cutting down each side before finally ending up at 310. Great job with this!
EDIT: Woke up with a fresh mind and found 308!! This path feels pretty good but this level has so many possibilities that I'm still not fully confident it's optimal.
The harder of the two, but neither are super difficult. Really amazing that you were able to produce two solid levels with this concept. Deserves 5 stars for the innovation.
