I'm not much of a rage game fan, but I really like where you're going with this game. not sure if the little blob guy fits in with the big ominous monolith.
Sound design is nice, I'm not sure music is needed but maybe adding some ambiance like wind and rocks falling in the distance could increase immersion.
not sure if you had the rolling mechanic in the last DD but I really like it.
keep up the good work!
