Played a whole bunch, rarely got thru level 2, only got thru level 3 to the final boss once (and failed). It's hard! Finally had to put it down when I experienced the high of beating the level 3 boss for only my second time, followed by the absolute low of the final reward chest being a game-ending mimic. Whew. (Feels like this shouldn't be possible!)
I eventually figured out that it was important to tune my deck by kindling something at every opportunity (like any deckbuilder). And for the first few runs, it was key to use Snooze cards to grind level 1 or 2 for a better deck before proceeding. Then more Snooze in level 3 until the RNG delivers a level configuration your party can pass.
I love the simplicity of the gameplay with the large number of possibilities for deck/hand/level combinations. The art really lines up with the AGBIC source art, too! Music's great, sound effects are varied and fitting, and there's good variety in the way the encounters play out. Great work!
