Well, its $400 of only a $1000 goal (now needing $300 or so)
Honestly that game does not seem like anything special, could be ok enough fro ma gameplay standard but the art looks kinda bad, looking like a odd mix of Sega Master System sprites with modified Kirby's Adventure sprites. The worst part about it is the inconsistent pixel sizes. Some characters and objects have big pixels (like the enemies), some have small (Like the BG and leaves of the trees) and worst of all, the player bird has large pixels for the body shape, but small pixels for the face. Some parts of the land has outlines, some does not, and color choice is not very good. It all just kinda looks armature, I've seen worse and it would not take too much effort to fix up.

With all that said, good luck to him getting the goal.
