Very nice!

Bricks in the wall looks great, but the Dragon is just awesome!

colours from "Alex the aligator"? :)

 Thanks for your comments. I've added some game interface elements. Onek - your edit is great! ;)

32 colours is insane for something that looks so monotone. I think the dragon could benefit from having his lineart cleaned up a bit and i agree with the HUD. Great so far though :)

I agree that there should be a HUD but it still looks cool without one. 

Though the color count is very high. It could be easily cut to 16 without noticing.

i think this would benfit from adding  lifebars and stuff to make it look more like a actual game, also i think it would be nice to let your sprites cast shadow on the wall to give it a more dungeon-like feel... also you got way to much colors going on, ... since it already looks gameboyish you could maybe try using only 4 colors, thats how much a gamboy had...

heres an edit with 7 colors, shadow, HUD
