I gave up on mobile gaming years ago once they all started to become freemium lootbox-opening waiting games. This is not one of those! This actually makes me think mobile gaming is not, actually, 100% trash! The gameplay is fairly standard Slay-the-Spire-esque deckbuilding roguelite, but it does it well enough with no weird catches (ads, microtransactions, etc.). It's pretty short but I enjoyed my time with it, worth a look for sure.
