Yes, it's a historic title so people expect it too look the part. Surprising so many people wanted this, I would have easily picked something else but it's all good, I made a cover for it as well, it's a nice classic after all.
Update: I just found out you made a H.E.R.O. 2 version for PC which already has better graphics, which is quite cool. Maybe that version is coming to C64 too one day... :)
