I think the game would benefit from some wall of fame or achievement system. So it would not just about beating the dungeon , but to collect things as well. Overarching achievements:
- Beat level 30
- Beat 20+ level on a monday
- Have 30+ str when you beat a level
- Have 3+ luck when you beat a level
- Have 1000+ HP when you beat a level
- Have 50+ defense when you beat a level
