This is a very very interesting concept! It is very innovative. I like the artstyle a lot, especially the tiles for examples. I did end up moving off the map at some point but I was able to go back. This must have been a lot of work to do, good job! I love the eerie vibe to the game, though I do think some more audible sound effects when you step on a trap or pick up the sacrifice would be nice. Nice that there is also multiple characters to play, though I did just spam the doctor hehe
I did notice in level 3 my items disappeared after I bought them, which was weird. Not sure what happened there.
Keep up the good work!
