I think spike gun should pierce through an enemy if it is a killing shot.
picking up broom or pinata shouldn't drop your weapon, if you pick up a crossbow or flamethrower just before hitting a broom, once you finish the broom ride you go back to pistol with enemies flooding into the screen.
picking up the spike gun gets you killed very fast. likes other have mentioned without the ability to prioritize certain targets being problematic, spikegun is one of those problem since much of the DPS from this gun is wasted.
The Heroes' Traits and abilities need to be optimized for better combinations, also with respect to their Custom weapons. Take a look at Wesley, as a Unique he should have a better set that makes him a solid endgame Hero. What good is EXP+ and GOLD+ in the final stages?
What good is Peacekeeper's +50% Headshot damage on Heroes without headshot trait/killstreak.
A really annoying bug for gunslinger is that her "Gunplay" trait doesn't reload her secondary weapon, only her primary. So sad we can't use a Bolt Sticker & Gunplay combo.
only local saves? you have to take into account that its likely most people who play games on kong have to clear their cache regularly. we need a server to hold our game progress.
