Shrine Of Cards was a nice change of pace from the usually rogue-like card games that have popped up the past couple of months; while it follows the standard "do actions, get different cards per run" formula, the game has a different end-goal: instead of actively trying to defeat enemies to get to some special ending, the ending comes from building a shrine that you must also occasionally defend. As you use cards to get materials to build your shrine, each new turn adds either enemies or special events that can both hinder and help you. Neither of these two obstacles pose a huge threat unless you don't manage your cards right (or if you're just really unlucky with the special events), and as mentioned by the creator, some of the cards really aren't balanced.
While the enemies range from humans that steal your materials or do damage to you to spirits that can steal your life, MP, or materials, the cards completely overpower them in terms of sheer utility; you start off with one damage card, a few healing cards, and material cards. Every 7 days, you'll have a pick of 3 cards. The cards range from more materials and healing to really overpowered things like clear all spirits enemies and gain 3 materials at a time (you need 5 to build a piece of your shrine). Of course, these cards come with MP costs or health costs, but the game feels overly generous at times with how much you have to work with.
All in all, for a game made on a time-frame that was a day shorter than expected, it was done really well! An average playthrough would be around 10 minutes, and I'd highly recommend it if you're looking for a laid back, rogue-like card game
