If you're going to make a game that has things you can buy that cannot be obtained otherwise, you might as well take it down from the websites and sell it on your own. Otherwise players like myself who cannot buy items in game will have a disadvantge that shouldn't be present in any game.
Obviously your first game, but i'd say it does the job with a surpisingly smooth gameplay. You could keep the theme of snake and add some more unique factors to it, the first being that you need a grid - like background, for a more virtual look to the game. The placement of bonuses is always slightly off. if there was a grid as background, the bonus would be in the corner of a square, not in the center. Such thing puts me off. I also obviously suggest some sort of bigger challenge, like enemies, sound and music, as well as a better interface with unique text and a nice graphic. It bugs me to be able to click the score, and see the flashing green line, marking me where i clicked.
Such game could be called Snake Infiltrator, and if you do get the chance to turn the simple concept of snake into a much greater game, you will create a game with lots of potential.
Good luck!
This was mostly an experiment! Bubble Tanks 3 Wich BTW will be out TODAY (OMGZORZ) will just fuse the De-evolution with the tank creator, the free roaming, bosses, new updates EVERY DAY (Avatars, Enemies, Bosses) and a new parts pack every month wich includes LOADS of new stuff at a low price of 4.99 USD! Also there are MANY more stuff than in BTA, so this means Bubble Tanks 3 will be the revolution: The best game of the series.
ALL HAIL THE BUBBLE TANKS.
