We have to inform the player why she is dead. A description should be passed to the end screen describing the cause of death; say "fuel finished", "hit enemy", "Players choice" or whatever. make it cute and fun.

Some of terminal behaviors may misfunction after exiting the game including that sometimes cursor disappears.

in a line, or maybe later a few

-------     V   ------
-----             ----
-----     .      -----
----      A      -----
S:0020 F:015 ...

to keep the view free.

In this case it's obvious that player will lose the game.

Show the best score and player's score in the game over screen. Make it clear if player scored a new highscore. Highscore should be kept consistent for future sessions.

Accelerate the avatar's speed when the player holds down a move key, instead of a constant speed (remember to reset the speed when stopping). This would greatly improve the game feel and control if polished enough.

سلام جادی
من سعی کردم این بازی رو با گولنگ بنویسم. خیلی باحال بود.
ممنون

to make the water more "realistic" ;)

maybe more random, if the river has a small width... less random, if it is wider

Pressing 'R' key could be used to restart the game (reset score, reset fuel, refresh map, refresh player and enemies position, delete any bullet etc.)

In this case it obvious that player will %100 lose the game.

It would be a nice challenge to shoot (and of course implement) moving enemies. There could be various types of enemies with different movement patterns (vertical, horizontal, or anything in between)

I wanted to ask if is it ok to add Elapsed time text next to the score text ?

I kindly request the addition of build binary settings to generate binaries for both Windows (10 and 7) and Linux operating systems

I was wondering if it is possible to create a pause menu with crossterm.
The idea came from those dialog boxes we see in curses apps, who seem like popup illusions, but I don't know if crossterm has this functionality.
Any ideas?

... especially, if "wasd" are control keys...

make faster airplane after some time or add level with different speed .

River goes too much left after a while and never goes to the right again
which may be an annoying experience
i think i've found the origin
check this code snippet :

    // draw the map
    for l in 0..world.map.len() {
        sc.queue(MoveTo(0, l as u16))?
            .queue(Print("+".repeat(world.map[l].0 as usize)))?
            .queue(MoveTo(world.map[l].1, l as u16))?
            .queue(Print("+".repeat((world.maxc - world.map[l].1) as usize)))?;
    }

i think the line :
.queue(Print("+".repeat((world.maxc - world.map[l].1) as usize)))?;
causes this behavior.

panicked as soon as game started with

Speed up the gameplay once the player reaches every 100 scores.

Bomb entity can be added to game in order to blow a radius and player can't pass too close to it. if so player dies. Bombs can be introduced by an integer like "5" and subtract every frame and eventually go off when reached "0" and in the meanwhile if player was too close (1 cell away for example) he/she dies.

(just trying to find a better use of function "hit_with_margin" added in PR #10 & #21 )

check for the screen size and do not show the start / end ascii arts of the page is not large enough

gfx: much more complicated as for the water, as it could not be just random

or maybe grassland where it is possible to shoot over. and woods, where bullets hit a tree.

Proposed enhancement.

after pressing 'q' "Good game thanks" banner shows up and after pressing any key game just exits.

... just for debugging to test new features...

btw: if it is not an airplane, but a boat now, the default speed seems much to high for me.

it is good to show player final score whenever game finished

if you played the game, and have ideas about the fuel start and fuel addition values, please comment.

i uploaded a screenshot for the sake of PoC
which shows the output of git command after exiting the game.

Currently, moving the player quickly is challenging.

To achieve this, you must either rapidly press the arrow keys to move the player in a particular direction, or if you hold the arrow keys down, the player starts moving with occasional lags, advancing pixel by pixel, which renders the game unplayable.

My suggestion is to introduce acceleration to the player's movement. When holding down an arrow key, the player's speed should increase gradually, depending on the duration of the key press. Releasing the key should reset the acceleration to zero.

This adjustment would allow players to evade enemies and navigate around obstacles more smoothly

we should inform / show the player that the game is paused. Say a box or something.

Note: please do not do this one. I will do it on screencast.
