Despite starting with 0 gold and the first upgrade in the skill tree requiring 10 gold to purchase it, I was able to purchase it and therefore be left with -10 gold. Also, there's big buttons besides the resources which you can hit and be granted extra resources. It kinda breaks the game. Can you add Wiimote support?
Thanks for catching this. The upgrade purchase bug and resource debug buttons are definitely not intended and will be fixed before the next build. The gold system should block purchases when you cannot afford them, and the resource buttons were debug tools that should not be visible in the demo.
Wiimote support is probably not planned right now, but I respect the chaos.
