I'm happy you provided a downloadable version as I had it downloaded and I played it while itch didn't work. With so many games in the Jam and as the werewolf part of the second level might be above my skill level (I rarely even reached the later parts when you're getting chased by several ghosts as the bats especially always kill me before that) I eventually switched to another game but this is easily one of my favourite games of the jam.
The tunes are amazing, the art conveys NES perfectly and I specially love how smooth the game is to play, in both phases. I love the part where I can use the items possibly the most, it works super well, but the werewolf part is great as well although I'm very bad at controlling him. The different threat the different enemies propose is great, I love to hate the bats and the spiders or the ghosts are also super cool.
My main minor caveat would be that the way items are carried between levels (or half levels) or when you die doesn't seem to work that great, it's unintuitive and sometimes dying is extremely punishing when you have no item left. The enemies being really slow can also sometimes be a problem when you're waiting for them to go all their way through a spider so that you can burn them.
Great game, thanks for sharing!
