Heyo, playing this.
-My default attack feels like I'm slapping skeletons with wet noodles with how weak it is.
-The alternate tap attack does about 5 times damage and doesn't feel particularly slower.
-I was defeated by the crystal that says you should use your abilities. I tried every one, didn't know what any of them did, and got slapped by the crystal. Then the level completely restarted.
That was basically the end of my patience for it right now. I played close to 60 demos so I'm a bit tired. I would say your tutorial needs work, and it seems like we're missing some story cutscenes before this. With the way the dialogue is presented, it feels like we're supposed to know where this dungeon is. It certainly doesn't immediately look like an undead castle, which makes me think the game was supposed to talk about it before. Keep up the progress!
