I think that quest to ather 10x Snifish material is bugged - i have 20 samples in inventory but I cant do anything with it. Dr L just says "I wish You good luck on your path"
The itch.io version is 0.1, which is the latest. Strange... the others who reported this problem said that the problem was solved after downloading version 0.1, I can't say why your case is different. Just to be sure, did you return to the third area of the coastal area and then go to back to Dr.L?
