I'm playing Crypt of the Necrodancer, got in on the sale like everyone else, it's a lot of fun and it can get surprisingly deep. One of those games where you constantly die and have to start over and over but that's part of the fun as you slowly understand how to deal with all the different situations it throws at you. It's almost like a turn-based strategy game, except it's based on beats rather than turns. The soundtrack is insane too, I can't wait to hear what they did with Zelda music, but I won't consider getting Cadence of Hyrule before I beat Crypt of the Necrodancer.
I will because I hope/expect Cadence to fix some of the things that I feel really holds back Crypt. Unfortunately attacks are still mapped to the movement buttons when I really think it should be it's own dedicated button. However, having permanent upgrades other than health will be very important. The starting dagger is trash and even after wiping out every bonus item possible I still get runs where I don't get a decent weapon until the third level. Also it looks like healing will be much more common in Cadence where it was a massive pain in the ass in Crypt.
I've made it to the fifth dungeon because the music is that good and it's easy to pick up whenever, but it is a very flawed game in my opinion and I've got no problem moving to a superior sequel before finishing.
