The upgrade to range 14 kills the player. It stops trying to dodge. Other than that, fun idea for an idle game. Maybe kills can set you back a level or two instead of back to zero.
Yeah. None of the upgrades should be a downgrade. No way should attack range cripple your movement. Basically, the only thing that should cause trouble is wasting money on healing when you don't need it or even upgrading health capacity when you need to upgrade damage or attack speed or something.
