Though you say you forgot it, the limitation still stand in my opinion as you are only equipped with a sword and shield.

The game really needs some variation to the levels. It's all on one height, the only 'difficulty' is the jumping across gaps, and for the most part you can just spam left click to kill the enemy without any real thought.

The animations are rather clean. All the assets look like they came out of an asset pack, please take this as a compliment if you created it all yourself as all the assets work really well together.

Level 5 should have been some sort of boss fight, or something more challenging. It's weird to just have 'thanks for playing' taking up a level slot. Though having selectable levels is always a good idea as it makes it super easy to expand the game.

Audio would have added so much more to this game. It's kind of dull without it.

There are a couple issues I found in the game:

If you attack an enemy after they start their attack animation and before they hurt you, their attack animation is swapped for their hurt animation. This leads be to believe I have stopped their attack. Turns out I did not stop their attack and I've been hit.

I'm not sure how, but I took a hit, defeated the enemy, got a heart back, but when I was hit again it took away my middle heart. I was then hit one more time and I died. This happened on level 2.

Overall, I like the game visually, it just needs more activity to make it fun. I think the limitation is applied and the theme is well met.
