This is kind of an odd story. 13 years ago I started learning assembly language for the calculators TI82/83+ and made this game on my spare time (I was a student back then). During the recent lockdown I had the idea of porting it to PC as a pet project, and I added a full support for controllers, a kickass soundtrack, some better mechanics, and so on.
Anyway, Castlevania Prelude of Chaos is a love letter to the GameBoy/NES era and it's an action adventure game with many bosses, weapons and whips.
Hope you enjoy it
