I played the first level and was intrigued. I would like to play the whole series, but I'm not sure which order to play them in. What would you suggest?
if you're into just the platformers: Proto DERE, DERE EXE, DERE EVIL EXE, then HopBound
if the whole series, just put in Sorority Rites and The Last Yandere after Proto DERE :)
