Thank you! The difficulty was something I could have used more time to tune. I think that enemies with multiple hit points would be a natural next step in difficulty. For the purposes of the Jam, though, I didn't want to make it too hard, especially since there are two ending screens and I didn't want to discourage people from playing through multiple times to see both. That's also partially why I made a separate endless mode where players could simply survive for as long as possible.
