Gameplay
Move around with the arrow keys, gather lemonade from girls in windows to fill your bladder, unleash the fury with the A key. Pretty simple, really. Phase 1: The giant turd. Tosses turdules at you and breathes diarrhea upon you in a stream.
Stay high, and don't fire at him when he's doing his diarrhea breath at you because you may incidentally lower down into the stream, and that just doesn't help anybody.
You can shoot the turdules, but you don't really gain anything for it other than preventing them from hitting you. Phase 2: The giant robot. Fires missiles at you and breathes fire.
Stay high and forward and he can't hit you, or else just pay attention and dodge the missiles, and move to the top when he breathes fire. Phase 3: The fishbowl. Fires slow-moving blue ice at you from the front, then goes above the screen and drops turdules from above.
Pretty simple, just dodge, charge your bladder, and try to fire at him when he's moving upward rather than downward.
Also the highest hit points out of all the phases. Phase 4: The escape. If you have enough pee stored up, you can stop the enemy from escaping.
Basically, you have 10 seconds to try to kill him; you win either way.
And now, without further ado, here's a complete gameplay video of a perfect game getting all 7 medals.
