Congratulations on finishing your game! I really like the concept here and your pixel art and presentation are done well.
I felt like the movement and combat was a bit too slow and clunky, I was barely able to keep out of the orcs reach whilst doing my best to attack whatever I could without loosing health. I know the objective is meant to be survive 3 minutes, but as player I felt I had no other tactics than to run and hope for the best, making the character feel underpowered and slow. I noticed that I was able to move diagonally faster than in a single direction and that gave me a bit of an upper hand but generally this is considered a bug.
I also thought the enemy arrows were way too slow, and they also seem to change direction mid-flight though this could have been my imagination or a weird effect of being able to outrun them and having them move around the screen in unexpected ways. As a player my general expectation is for arrows to fly straight and quickly across the screen. This would make them harder to dodge, but I noticed I could attack arrows to destroy them but I felt like some more options could spice up the gameplay, for example, being able to deflect them with a perfectly timed attack, or perhaps adding a shield to be able to block (but shielding slows movement speed for example).
I think you've got a great start to some really fun gameplay.
