i feel incredibly stupid but im currently stuck because i cant figure out how to talk to anything. i was able to talk to chase after he let me loose in the world by pressing enter or clicking on him directly, and i was able to with lola as well, but i couldn't talk to any of the other characters.. im really really confused
if you haven't yet, go to the last room and talk to the face in the ground, then come back and talk to lola. After that you need to press 1, 2, 3 or 4 on your keyboard to do different interactions with the characters. (I don't remember which one is talking but you'll know by an icon with an eye that pops up after you press the right key)
