Repetitive,ugly characters,decent story

err..

Not that great, hard and sluggish to play (that isnt meant to be a joke, you really do need to speed it up) your other stuff is quite good and while this isnt blamworthy it does need vast improvements!

jumping slugs and bad grammar hm

wild guess but english wasen't your best course right?
the story was original but the game isnt AT ALL. anyways jumping slugs?
Its a snail by the way, not a slug.
I agree with Bezman that that one red thing is a pain, even more so because of the evil slug just above it. however if you use the bumb (or is it bump?!) from the other slug you can easily get it.
more reviewing: the game is okay for those old atari consoles, but well its been a couple of years since then. graphics arent that great but at least its not stolen sprites or something similar.
gangsta slugs rule the rest of the game doesnt. and perhaps its just me but bad spelling is a big mistake in flash games, movies etc. it just make it look so corny and fake. barkeep, a rounds of dictionaries and spellingscheckers for everyone!

I didn't get past the first level...

There's a red thing at the top right, which I think you need to get, and I couldn't seem to get to it.

You don't seem to be able to jump down from platforms. Jumping from the platform one down will take you up to far and jumping from the platform 2 down doesn't take me high enough...

(I might well be wrong and if so, please explain the way to do it to me.)

Other than that, the most important thing you need to sort out is tha speed at which your character moves. That one trait of the game makes it so tiring and unplayable...

Other than that, you've done a decent job, so well done.

However, you really need to speed up the character before it has a chance of being playable.

I hope my review was useful to you,

Slowly gets worse...and worse...and worse...

Sorry, the intro had me intrigued, but the game is basic and crude. My slug moves at like a quarter the rate as the bigger ones do, for Christ's sake! A better platform system would be beneficial to your game, as would a better AI system.
