Encountered a bug right in the tutorial, after opening the safe room I couldn't go anywhere but there and the room where the key to it was. As I found out on a second try, the way to the shop was also bugged so that I was accessing it right from the safe room, therefore I couldn't get the sword either.
Another one I just got in the tutorial as well is that in the first enemy room I couldn't take out the sword? The guy just kept hitting me and I wasn't able to do anything despite having the sword already...
I think it would also make sense if there was a pause menu on ESC? It's weird that you have to hold it and that it only closes the game and you can't exit to main menu...
I really like the sound and visuals and all though! It's pretty cool and I'm enjoying it so far!!!
