I beat the game and save our protagonist from DOOOOOM! That was pretty fun, kinda reminded me of Slay the Spire in the artstyle for the cultists (Slay the Spire is my favourite game so it's a compliment).
It was fun and simple, I just wish there was a bit less walking since there's not much to look at between fights and you have to redo it all over again if you fail. Maybe adding some spooky decor and greenery would help? Or have it be in a straight line, in a temple as you're fighting your way to freedom?
As others stated, if you have three items, you have to use the bottom one, the others won't work. That's the only bug I noticed.
I had fun!
