The longer a run goes on, the more likely it seems to be that the app will crash and you lose everything you gained on that run. There’s no way to save during a run other than go back to the main screen which will end the run and get rid of all your buffs. If you could save during a run after a battle, then at least when the app crashes you could go back and only need to redo the last fight. I don’t even know when the game gets hard because I’ve never gotten far enough in a run before the game crashes to fight something that doesn’t get obliterated in the first 1-2 hits. This game will be unplayable until they add an autosave after each battle or at least every level up/upgrade
Thanks for the detailed report and feedback, and sorry about the lost run progress. Version 1.6 adds run recovery for interrupted dungeon runs, so after restarting the app you’ll have the option to resume from the last completed battle. I also fixed a crash that could happen when double-selecting a merchant purchase too quickly. I really appreciate you calling this out, keep the feedback coming!
