Alright so, I'll try to give an honest review of this.
In all honestly, I don't see any problems whatsoever with this game to complain about, it has nice graphics, I always love some god old pixely style game, and this is a pretty solid one. It may look like Kirby, but it can be fixed.
Animation-wise, I think it's pretty amazing too, and although I've no idea how to animate or how hard it is, maybe adding more action animations would be sweet.
A slight bug I found is that while crossing a door, if I hold the w/up key indefinitely the character will get stuck until I do otherwise, but nothing game-stoping either.
This is a great demo overall, and if more creative creations come fromthis I'm definitely looking forward for more.
