This game has a lot of potential, but there are quite a few things that could be improved.
Sometimes it looked like my sword clearly hit an enemy, but the hit didn't register. Even when I did land a hit, enemies could still damage me at the same time. The jumping also felt a bit janky, along with a few other gameplay issues.
That said, I liked that the game was challenging, even if a lot of that challenge came from these rough edges. At first, I wasn't sure I'd enjoy how the game played, but I ended up sticking with it and had fun trying to make it to the end.
With some polish and bug fixes, I think this could become a really enjoyable game. Good job!
