I'd like if the different characters each had individual ways their projectiles flew, the arrows could arc, the Mage spells could perhaps fly in a normal straight line and then maybe the bombs could explode when they hit the floor or something? just an idea :) 3/5 for now.
Shrimp boat seems bugged, 25 unlock didn't happen by itself, i got to thirty and still no unlock. 50 didn't unlock by itself either, i had to buy a shrimp upgrade for the unlock to trigger.
i see they've realised that 'watchers' were overpowered, they've increased their speed from 5 to 9, or my game is broke. :P anyway they were my favorite while they were.
