Hey … not trying to diminish your work. Konami tolerates fan projects and using their assets as long as they go to non-commercial fan projects. You are opening yourself to DMCA takedown by asking for money.
They should be better at enforcing it too, Castlevania III Revitalized has been around for years with the creator charging money for it. Feels scummy to take money for what's essentially just a remaster of a copyrighted property.
