Item stacking should be implemented to avoid performance issues (those mining lasers create lag easily with away from you)
From the moment I saw this game I wanted it to be on my Android. It has the look. The size of an island is perfect for the screen size of a phone. The UI won't need a whole lot of tweaking for swipe and tapping, just a tool bar and inventory button. For throwing you can hold and swipe. Can just swipe to collect resources. It has the right amount progression that you feel you can get somewhere in the 10 or 15 minutes while waiting for the bus. Appeals to a wide audience with simple combat, magic, and farming mechanics. Perhaps when the performance is maximized.
It also has that relaxing not very mentally challenging gameplay that allows people to stop thinking about the stresses of life. I read that you are porting it to switch. That's definitely a good move. I just love the graphics. Reminds me of something you'd see on the game boy color back in the day.
