i was wondering if you could add paths for different upgrades.
these paths effecting all turrets and upgrading your witch, staffs, hats, a gem in your staff, or optionally a broom over a staff.
staffs would be a unique upgrade to your turrets as a flat increase in a stat or two, hats should shake up the game, but have a drawback. magic gems could be dropped by enemies, or mined, giving a temporary boost, and a broom over a staff increasing speed and allowing two extra fruits or a turret to follow you.
