I.c.a.r.u.s. 2.0

Just started the Argon Assault section of the 3D course.

The working title of my game will be I.C.A.R.U.S. 2.0

The aesthetic theme will probably the same as the one in the course (I am tempted to make the player one of the aliens but I don’t know yet if that’s relevant).

The main difference will be in mechanics:
I want to make the player’s ship only able to fly for a limited amount of time (shown on screen either via HUD or somehow diegetically) until it burns out and fails the game.
To cool down, the player has to toggle flying off and be constrained to hovering over the ground.
The catch is that firing is only possible while flying.
Flying is on while the right mouse button is held down.

Maybes:
the heating is paused by firing, but ammo is limited (adds an unexpected layer of strategy to the game)
hovering and flying speeds are substantially different. which is greater and what gameplay does it create?

used the Unity 2019 samples. used them pretty badly, but this is a placeholder.
