Fixes:

• Level restart works correctly.
• Fixed transition between levels.
• The bomber returns to its path and is ready to destroy the player's ship.
• Saving and loading data is now correct.
• All planes fly correctly and try to destroy the player, no false self-destructs.

New:

• Gamepad control button settings.
• Implemented test auto-aim.
• Made a hardcode mode for enthusiasts and achievement hunters (in this mode: only 1 life, no restarts and saves).
• Delays have been created before the start and end of the game, there are plans to put a siren or other sounds of preparation for battle there.
• The player now has a reload every 10 shots, it's making the game harder.
• Made the logic of level completion when the player dies, the player will be asked to complete the level again after death.

Widgets:

• Animations for the appearance / decay of transitions between menu items.
• Fixed visibility of start button.
• The continue button in the menu is not available if there is no saved game.
• Added warning windows for deleting saves, exiting the game, restarting the level, returning to the main menu.
• Added images of the number of bullets, rockets, barrels the player has.
• Added color scheme for the player's life bar.

Update:

• Improved the system of respawning enemies, now it is more optimal and more productive.
• Paused between enemy respawns.
• The logic of saving/loading data has been rewritten, now they work better, more clearly and in one file.
• Rewritten/optimized the main functions of the interaction of game elements invisible to the player.
• Planes collisions have been updated to be smaller and clearer, making them harder to hit.
