What is sully project? Sully Project is a currently in-development visual novel for adults only, about an anxious man named Samuel Hart finally making the big leap: moving in with his soon-to-be-not-so-long-distance-anymore monster boyfriend, the big and friendly Sullivan. The two try to make the most out of the time Sullivan has taken off from work before he has to go back to his regular schedule. Featuring no stakes and very little drama, Sully Project offers a relaxed, cozy experience with optional sexual content.
