Yes! That was actually my inspiration. I love this game so much! Always liked the "combine items" system, that's why I wanted to implement this in my game, too.
I discovered it through my Ambernic, great game. Yes the “combine items” is a cool idea. I think your system has more polish than even stranded kids. I found stranded kids difficult at first, lots of trial and error over combinations. I think I had to look for online help! I love the visual ques you’ve put into your system.
