I’m really liking it so far, with some caveats that the developer is addressing. The pixel art is gorgeous and evocative, and well animated. The sound design is also extremely good. I like that it’s playable one handed in portrait, though more often I’ll use both hands. The core gameplay loop (enter mines, dig and look for dungeon entrances, delve the dungeon and get treasure until you die and return to town, buy upgrades and repeat) is very compelling.
There’s also some jank around the edges. There have been some crash bugs, some ways to get stuck enough that you have to quit the app to abort a run, etc, many of which bugs are fixed in today’s patch. I’m finding progression to be a challenge due to my limited skill, and also there’s an upgrade material that I just can’t find yet, which is sort of maddening. It’s definitely got me hooked, though, and if a mobile portrait-orientation roguelite with a really compelling presentation is appealing to you, I’d say it’s easily worth the price. Based on the developer’s responsiveness and track record from previous games, I think it’s likely to keep getting better.
