Lead developer here,
Thank you so much for enjoying our game! Your feedback really means a lot to me.
The [NUMBER_HERE] bug was fixed pretty much right on the deadline, I think it shouldn't occur in the future. The health issue was an oversight though, it will be fixed as soon as possible.
In regards to the enemies, they are coded to have different damage types (snake poisons, jelly cube hits multiple times, dragon burns etc.) but I just didn't get around to implementing these before the deadline. And using Freesound is a good idea, I'll use it in future game jams!
Otherwise, I think you nailed perfectly what I would love to improve about this game / future games. Thank you so much for your feedback!
