Upgrade-able turtles with cannons where each match is fast-paced, chaotic, and more intense than the last!
Two sticks and two triggers is all it takes to jump in! Left hand for moving, right hand for shooting.
Slay your friends by sniping them with exploding bullets, running them over with a dash attack, or by pushing walls into them to squish their little turtle bodies.
Dash into enemy bullets to reflect them back at your opponents, or dash into yours to knock them in a new direction.
Use the recoil from your cannon to set-up a better shot, gap-close, or out-maneuver.
Only the losers of a round get to pick upgrades, so eventually, anyone should be able to win.
... right?
Go wide or deep with your upgrades. Combine a bunch together or invest into one to get something equally game-breaking.
Examples:
Rapid-fire bullets that track enemies and pass through walls,
Laser + cloning yourself multiple times to get an army of laser turtles
Just get a sword and make it really, really long.
