Thank you! Here I was thinking we made the game too easy...
We are currently working on an update that will add more roguelike elements and hopefully make dying less frustrating. e.g. Permanent upgrade shop to make runs easier over time and more control over how difficult the game is. More builds to allow for different playstyles. More enemies and attack patterns. We'll keep your feedback in mind when we are rebalancing with the new content.
This is also the first bounty of many planned, so you're right that it shouldn't be too difficult.
