This is a good start to the game's development. Having cards and equipment interact with each other is fun, and the limited item slots leaving a stage makes it so every run into a dungeon offers a choice between grinding for exp or just grabbing what you need and getting outta there. I also appreciate how the crafting system is superior to buying items in the shop, but not an outright replacement to it.
That said, it is a bit rough around the edges. The game's difficulty curve is a bit odd. Normal enemies become farmable far before the boss of the same stage is, which makes thay choice of "exp vs items" I mentioned early became a choice of "Do I farm the one I can't complete, or the one I can?" But that means gold is hard to come by, since you do need to clear the level to get coin. Which makes improving your deck a bit awkward, as CP is only used to buy packs, despite that you can get CP really fast by just selling cards you don't need.
Also, when I opened the game today my save was gone, and I don't know why. I don't mind restarting, nature of playing a game still in development, but I'm just confused if it was a side effect of updating (as I don't remember the Login button being there), or if my phone did a funny.
