Made a tank with 2 apocalypse cannons (think that was the name, the one that kills everything) and 2 of the mine layer ally secondary. Fired them in an empty bubble. Game froze and started looping an animation of some bubbles bursting out from my tank.
Otherwise, great game.
Decent game, overall. I think it would be a lot more playable if you could hold down a key to repeatedly use an ability, rather than mashing a key for minutes on end.
