This certainly was an interesting one. Let me first say that I haven't beat the game yet, but I still found it pretty neat! Though the Time-Traveler's sprite was hilariously creepy to me, with legs that faced forward when he walks to the side. When I crouch, it seems he's in the fetal position. Awkward.
Anyway, this has been fun so far. However, I do have one complaint: killing the Morlocks is hard! There was one segment when I assumed you wanted me to kill one with a boulder, but the landscape was made that the boulder could tip in either direction . . . and I pushed it the wrong way, down into a straight hole.
I mostly avoided the Morlocks (again, haven't beaten the game yet), and I've found one key. Nice work showing us the number of keys in the beginning.
I'm going to go beat this game. Really like this so far!
