As a huge fan of Dragonsweeper I absolutely love this. Thank you for making it and sharing it for free (with the added bonus of no data collection / network requirement for the Android version, noice!).
The only thing that could improve this game for me is if you added support for auto saving & resuming the current run. Roguelike purists might disagree, but I think it would be a great UX improvement especially on mobile if there’s no pressure to finish a level in one sitting.
