If you wanted to create an incredibly hard game, then you succeeded for 200 %! The game concept is good, however, I think that you exaggerated it with the difficulty. I understand that you wanted to create a hard game, but this one was too hard. I also don't understand why the game's name is Duelling with a Shovel - for me, it didn't seem like I was holding a shovel! That's probably caused by that the graphics aren't very good. I'd recommend you to make better graphics next time. And the probably biggest problem is about the bugs - there are so many of them! When enemies can't damage me, then it's bearable, but when the enemy disappears... that's catastrophic! However, I liked the music - it goes well with the game!
I'd like to know one thing - how is the final score counted? My score was 118.
