Really cool idea! I love how the game looks as well, some really nice spritework. I definitely feel the regen sort of encourages you to wait around a lot though. Maybe it'd be better to have killing enemies heal you? Regardless, really nice game!
Thank you for playing! We had an idea to make enemies heal you when you defeated them, but we didn't implement it due to time constraints and balance concerns. However, we will be adjusting gameplay to make it more engaging in the future!
