That was a good surprise!
My 1st thought on this was: "meh, must be a really short thing with good looking graphics", Turns out not only the graphics are god, and despite it's simplicity, it's somewhat challenging, having to carefully plan your supplies or upgrades, gives a strategic mindset to play, not only that the game's music is really catchy and awesome, even wen you lose or already have unlocked everything the game is still lot's of fun to play.
A sequel would be most welcome, maybe with a few new things like more enemies, magic or some story.
The android version runs really well on my Ideos X5, really great to have it on the phone just to kill some time, but I thought the game was easier on android than the flash here on newgrounds, the knight seems to attack more on the android version, but it could just be me and because I had already played the game here and knew the game, I probably thought it was easier on android.
Keep up the good work :)
