Great game. Though generally it's bad form to have any gameplay mechanics that involve waiting or repetition. Once you get through the corridor where you have to wait between each step, you shouldn't have to do that over again. And once you've gotten through the fire, the fire should remain extinguished.
Also, the text buttons behave pretty strangely. Sometimes it's tough to get them to respond. For example, they won't be clickable if they appear under your mouse.
The name vector medal won't unlock on NG for me. Beyond that, I haven't gotten the resident, dweller, snake charmer, or astral master medals. Resident and dweller sound related. There are two snakes the snake charmer medal could refer to. I guess astral master could be one of those medals where you get it by unlocking all other medals. Do you suppose you could release a secret medal guide for people who don't mind spoilers?
