Actually, those series are awesome, but are easy. I suggest making a forth one, with more opponents, make the dungeon longer, and have a strong boss. With those things, your game will be a litle bit better.
This game is awesome, but easy, short, and the level cap is not high enough. I wished this game had a sequel, because it is really cool. Oh and a skill reset point will be important.
This game is nice, I enjoyed every moment of it, but I was annoyed a little when getting the achievements, but once I finished some, I realized that the golden goose bonus is what is needed for the Bona-fide millionare and the Phoenix Pendant was helpful that time, the Poseidon Blessing is helpful also, so head for those two first. Good luck :) A second one will be awesome. Be sure to make tha soon!
A nice game. really, despite of this game's name this game really is nice, and some levels makes me, somehow, rate it higher and higher until I rated it 5/5. The levels are a bit hard, but still at the beginning it made you play it till the end even if the levels are getting harder.
I know too that you will enjoy this simple but interesting game.
Here's a tip when you are versus the boss, at first, don't collect any fireflies, until you could see 5+, since the snake doesn't eat fireflies you don't pick up, and, as hotsauce72 said, the snake ALMOST never travels the same spot twice. Heh, good luck
