The game now supports tablet controls! Most people (including myself) hate virtual d-pads, but I couldn't think of a better way to deal with controls for this type of game. Maybe I could implement swipe? Fortunately the game is turn based, which means a virtual d-pad should hopefully involve minimal headaches.
Cleaner Level Import:
When you copy and paste a custom level for others to play, it's basically a 250+ character string without line breaks. It also only accepts custom levels for import in the same way. I was able to code it so it will remove all line breaks prior to decoding the string for level import.
Now capable of accepting line breaks!
