just arbitrarily chose this to remap in my increasing efforts to test my new palette, gotta say it doesn't look half bad, figured I'd share
the ground was automapped to that yellow tone, I filled the top portion with another colour to test, this is by no means a hijack
oh and I actually like your colour choice too I might add
btw I like the designs looks quite interesting, got or planning on any more graphics relating to this? and I guess my main question is what are the likelihood it will go beyond a mockup? (and by all means keep persuading/nagging your brother or anyone else you know can code hah, or investigate some WYSIWYG game creation tools and see if it's viable to do it yourself)
you've gotten some good feedback in here too
