Doodle Bash is RivalPit's top-down kart-combat arena -- a hand-drawn take on the classic couch-battler genre where the goal isn't lap times, it's blowing up the other karts. You share a paper-sketched arena with rival racers, and four weapon types spawn on the map for whoever gets there first.
The weapon lineup is what gives each fight its shape: your kart starts with an unlimited-ammo Zap Gun as a fallback, but picking up a Machine Gun, Rocket, Mine, or Shrink Ray changes your options completely. Rockets splash on impact so they don't need a direct hit, mines sit and wait to punish whoever's chasing you, and the Shrink Ray doesn't do much raw damage but makes its target smaller and easier to finish off. First kart to 10 kills wins the arena.
Ammo matters more than it looks like at first -- the Zap Gun never runs out, so it's often smarter to fall back to it and stay alive rather than force a bad shot with your last Rocket or Mine charge. Mines are most effective dropped mid-chase rather than pre-placed, since a rival on your tail is very likely to drive right into one.
Four pickups spawn on the arena floor: Machine Gun (fast, limited ammo), Rocket (splash damage, only 3 shots), Mine (a trap that punishes chasers), and Shrink Ray (shrinks whoever it hits). Your kart always has an unlimited-ammo Zap Gun as a fallback.
First kart to reach 10 kills wins the arena -- there's no lap count or time limit, it's a pure kill-race against the other karts on the map.
It doesn't deal much damage on its own, but it shrinks whatever kart it hits, making that kart a smaller, easier target for follow-up shots from you or anyone else in the arena.
