Something like this is so basic that its often seen...its just a grid. We don't think these type of basic things fall into copying or RIPping anyone as who knows who made the first and that would be a copy too. Its just too basic. ;)
If anything, I find the problem with the BG is that it just may be too dark for the hue/sat of the sprite colors. For example, there is one black cat that is harder to see than need be.
Yep, I made the backround too but I feel as if I've seen it before somewhere. But yes, I'm making progress!
Thank you very much!
