Hey, ty for your comment on my project page.
As far as the backgrounds are concerned, I've now decided after your comment to make them fully painted, rather than pixel-art based, and keep their size as 100%, instead of cutting their image sizes down in half to save space. The only reason I did that in the first place is that the game was having a hard time loading on phones with full size parallax graphics, but I figure I have to release a PC game before any other platform can be thought about.
Link me to anything you'd like me to follow and I'll keep up with you as well. Thanks. : )
