The white tiles represents the area after scaling up. To make more yellow selections, right click to unselect and make sure you have more than 1 'scale up' left (top right corner)
Ah, wow. The visual indicators (yellow/white highlights) are a bit weird, but that aside, the game is really amazing!
Thank you! I'm planning on improving the tutorial for the mechanic after the game jam ends
Keep me updated! I saw that you're using KNI. I have worked with MonoGame in the past, maybe I can help out :)
I'll keep that in mind
