Algodoo

Hovercraft with 10 HP controlled with "A" and "D"

Win condition: blimp stops moving and shooting
Lose condition: player stops shooting (at 0 HP)
OR blimp reaches the end of the map
-----
Blimp boss is made of 3 types of weapon, all with 25 HP each:
Red frag cannons: comes with shield that defends
other red frag cannons, forcing you to kill them in order.

Orange firebomb cannons: fire lasts for 4 seconds, blocking your
movement and damaging.

Yellow gatling cannons: prevents you from fleeing.

Note that you can destroy the thruster (50HP), but should be done last
or you might get stuck with no opening to hit the blimp with.

In general, ice signifies that the object collides with bullets (shield and
cannon hitboxes, basically)
-----
While the hovercraft comes with high speeds and allows small bullets
to roll harmlessly underneath, it is prone to breaking on heavy impacts.

This scene is really hard and a complete nightmare for me to test. If you
are having issues, try taking note of where you need to be in relation to
the red frag cannon shots and position yourself to take down the red frag
cannons first. Remember that the blimp is moving slowly to the right and
aim ahead. Try to play safe when getting past terrain and note that the
battle gets much harder when you are on the bridge, the last structure.
