I liked this game.
I liked that the game managed to surprise by suddenly ditching the room formula.
Equipment drops seemed very uninteresting.
It's kind of weird that rubies served almost no purpose.
I found the skill tree oddly difficult to navigate. It could perhaps be laid out more orderly, and make it more clear which upgrades are affordable? I'm not sure.
Doesn't crit chance kind of work against Piercing Tip?
Doors only appear when they open, and then close before you go through. Kind of weird.
I agree with the comments about the skill buttons being in the way when you fight downwards in the werewolf place.
I noticed that it was often kind of easy to survive in the werewolf area, stamina willing, when the warrior died. He really rushes forward and makes everything more difficult. That isn't necessarily a bad thing, since speed is just as important as not dying, but it was funny.
