Wow, either spamming dex is way overpowered, or this game is extremely easy. I just entered the cathedral, and nothing can hit me. I can stand still with six enemies attacking me and HEAL.
This game is amazing. I bought the full version a month ago. Yeah, the levels can take a long time to beat, even if you're playing them optimally, but that's part of the fun of it. Make sure you've got a big collector base before you try to make a move!
