It’s a fun game but around lvl 6 the mini gun option stopped working just leaves green dots all over the screen, no big deal I stopped picking it but can’t complete the task but now at lvl 15 I can no longer upgrade anything and mini gun still isn’t working…definitely needs some bug fixed. I don’t really want to try to uninstall and reinstall just to lose all my progress and have to start all over, so hopefully these issues get fixed with some updates
Honestly fun game but needs a lot more upgrades and choices. The electric aura is a cheat code because you automatically win without moving. To make it a challenge don’t use the aura and enemies get tougher.
