The UI is clunky. The progression feels forced. Seems unbalanced. Too much unskippable dialog. All-in-all, a pretty bizarre experience.

A very solid deck builder. A well structured tutorial eases you in, and everything is heavily tool tipped, with most stuff having unobtrusive video demos. Mechanics are clear and straightforward but don't take that for lack of depth. There's some balance issues in some of the levels/bosses, but with the right luck with item and card draws most of it can be overcome. There seems to be a couple of bugs in the later levels, and some of the English isn't great, but looks like it's still getting regular updates. Super addictive.
