Don't expect this review to be nice
Snake clones never cease to amaze me, they seem to be the classic starting game for people new to flash and this one, like all the others, isn't very good.
My criticisms:
Choice of font - The font just isn't reasonable considering that this game has no references to the medieval or grunge (that's just my interpretation of the font). A plain simple font, even though it would've gone unnoticed, would have been more appropriate for this game.
Shoddy rendition of Snake - Snake actually made vague sense; eat pellets and grow longer. Ant Trail doesn't; eat leaves and get more ants. Also, the boulders were a challenging addition to what would have been an unchallenging game but the added an element of luck which is simple not good for a game you have described as "skill".
Lack of sound and music: Sounds and music are an integral part of the whole gameplay experience and without them, the game is extremely boring. Simply put, music would have made a boring game slightly less boring. However, if you do choose to put music in later submissions, please make reasonable decisions; trance and electronic music, no matter how enticing, don't work for every style of game.
Overall: Congratulations on having a crack at the flash world. Note where you went wrong and use these criticisms to create more and better quality games.
