So the Theme is basically Missing since you had no time to Implement :( sad
The Idea and Concept looks fine. I Like the Mechanic with the Sword swinging (had a hard time to find out how to Attack the Enemies)
The Graphics, sorry if i say this but HORRIBLE, especial the Borders, i feel like getting Motion Sick and those tiny grey Tiles feels like Cancer in the Eyes. You really need to Change that if you wanna Continue working on this Game.
Make the Wall Sprites bigger so they are not Graining like crazy. Maybe you use also a Grain Effect, remove it.....
I think you just overshoot your Project, Happens a lot, happens to the best, happens to me. But keep going and Growing, Better Games come with more Experience and at some Point u know what you can implement in a certain amount of time to a Game.
Keep working, Don't forget to take a look on Our Game.
