More like piece of chicken...
Perfectly functional game, seemingly no technical errors
Too short (and, no, being a demo is not an excuse)
Terrible graphics. The realistic main character and chicken collectables clash with the poorly drawn platforms and lack of background
Generic, repetitive music and general lack of other SFX
An overall lack of any real effort is evident
Overall, there's not much more I can say other than try harder next time. You seem like you could actually make a decent game if you put more effort into this; as I said, it's very technically sound. Now just working on getting everything else in working order.
CAN'T STOP WON'T STOP
FLIP JUMP FLIP JUMP FLIP JUMP
GOTTA GET DAT CHIKINZ
Found a bug on level 2, if you go backwards on the map, and jump off the edge, you dont die, just keep falling.
