Overall Excellent Game
Very simplistic game style (something I could probably emulate in VB) but entertaining. The game itself is endurance based (How long you can last, winning isn't possible) which is fairly rare to see in modern games.
The game is fun. There's no plot and the only objective is survival. Considering the lack of actual battle animations, I was a bit disappointed that there was not more variety of enemy types or portraits. This however, does not take away from the game. It is still fun and I'm sure whoever is reading this has already wasted a lot of time playing this game, and will soon waste more.
I'd like to write a small segment here, thanking the creator of this flash for adding a button to increase the game's speed. (located on top left corner) That was a very thoughtful addition to the game, It would have much lower replay value without it.
Suggestions -- More hero types, more enemy types, more art (Portrait and backgrounds) Addition of loot (Actual items, not just gold) and more stats (Luk, Dex, etc.) to add the possibility of hit or miss. (for both you and the enemy)
Overall: Simple, Fun, High relay value. -- Excellent Game. (Not recommended for those who want plot or complexity.)
