When I was young, I had a HUGE phobia for game bosses. I just felt incapable of beating them as they were faster, stronger etc. I remember reaching Schwartzenguard for the first time, I was really really scared, lost in an instant and went crying to my parents. To be fair, I don't remember what happened when I actually beat him. And what really surprises me is the fact that I somehow beat Uterus, Bubba and especially Bolly (which is one of the hardest bosses imo). Castle, Carrotus and Medivo levels make me more nostalgic than the other levels.

And, of course, I think I mentioned this before but I could never beat Devan. He was too fast for me to understand what should I do to beat him. I didn't even get to the second form :P

Edit: Did I mention these things before? I feel like I did, sorry if I did :l
