Needs to get harder
Very nice game but way too easy. I reached Level 300something and I probably lost because of sheer boredom. Even managed to fight the (Spoiler) twice in one run! - Hearts need to be more rare, maybe even do away with the fourth heart container or redesign the mechanic - You should only be able to buy the Recruit once per run - Coins need to be more rare (or shop prices steeper), one can easily buy everything all the time - Difficulty needs to scale more
