How are these ?
No place like home! <_<
What a long bridge! :blink:
How'd i get up here?
For the middle screen shot, instead of putting a path by his house, I'd somehow make it seem more like a dirt patch? I'd use diagonal lines with some shade of brown, so it looks almost scribbled in a way. I dunno, but it might be an improvement. Bear in mind I have no experience developing games whatsoever, but I still think it could work.
One thing I know you NEED to do is change the colour of depleted hearts from black to a darkened version of full hearts. It will look much better, imo. I don't really know how to tackle the grass situation, though. Sorry about that.
Other than that, this is looking awesome!
EDIT: The spiral house should be larger, with the path being much thinner so as to make it difficult to get up.
