I completed the game. Ending was abrupt as you get less runes than they are slots available.
I had fun playing the game. I mapped it and went a bit further after each death. I enjoyed how the first sequence does not seem doable at first but then you get to find a button opening a hidden door to a potion, that's cool. The second puzzle is good enough in the context, still my least favourite as the two other ones feature a cool, disturbing twist. I think the last one is pretty good with the rune of the place to the left but the hint to the right instead, I like this twist too. The game looks and sounds atmospheric. I like the cat, the statue and the look of the room of the second sequence, and the lighning effect around the potions is actually the best part of the art. I am really happy you went with instant movement as it's a game you're goint to replay a few times.
The one thing I don't like is that you can't see what type of tiles are to your left and right.
Overall this was a cool game, thanks for sharing.
