That was a fun and enjoyable puzzler, had me thinking on a few of those! Well done! I liked the atmosphere and overall visuals as well. I did run into one bug in the moon/star/heart room - When I was toying around with the configurations, then left to check the hallway, when I came back and clicked on one of the switches again, the game just froze - seemed like it was caught in a loop, as everything still played and no error came up, but I couldn't move or open the menu or do anything. Anyways, good job!

I liked what I saw! I got to the room with the save game sign and couldn't activate anything or leave the room though...  There is a screenshot that has content I didn't find because of that glitch I guess.
