Thank you for the game!
I liked how vibrant the art is and found the main puzzle genuinely interesting! It was hard but manageable, and after a couple of attempts did eventually won. Really loved the idea of the maze after I realized its purpose! All and all, the riddles were cool and you've done a good job putting it all together. Very impressive for your first Bitsy game!
As a little quality of life improvement for the future, I would suggest using a sequence list for the NPCs with long dialogues, that player has to interact multiple times with. This way after reading the dialogue for the first time they would not have to do it again later (especially relevant for the first demon).
I also found it a bit difficult to find a way to the room with the ritual. I think a small blinking animation or a more contrasting tile would make navigation in the house much easier.
P.S.: lovely fake-out in the end, it got me go "Whaaaaat???" for a moment
