Please set the background as a dark starry outer space sky, featuring distant stars, small glowing nebulae, and slow-moving space dust. The background should have a slight parallax effect to give a sense of depth and motion. All visuals must follow a retro pixel art aesthetic. The background should scroll horizontally as the player moves from left to right, creating the feel of moving through deep space. ↪💡 Consider importing and using the following plugins: @upit/tween.v1

I want to create a 2D platformer game similar to Mario, but set in space. The player controls an astronaut. The game should have high jumps and low gravity. Platforms should be made of space rocks, space station parts, and asteroids. Enemies can be alien creatures or robots. The player should be able to defeat enemies by jumping on them. The goal is to reach the rocket ship at the end of the level while avoiding obstacles. The background should show a starry space scene. Use retro pixel art style graphics. Gameplay details: – The astronaut should be able to double jump due to low gravity. – Add subtle jetpack effects (small pixel exhaust) when jumping. – Include moving, crumbling, and rotating platforms for variety. – Levels should get progressively harder with more enemies and traps. – Traps include laser beams, spike pits, and spinning satellite parts. – Enemies include walking aliens, flying creatures, and robots that shoot. – Enemies drop points when defeated. – Collectible items: glowing stars or crystals for bonus points. – Add checkpoints and respawn mechanics. UI & Scoring: – Score should be visible on screen. – Health is shown as 3 pixel hearts. – Extra lives can be earned through points. – Level ends when the astronaut reaches and enters the rocket ship, which launches with animation. Style: – Keep all visuals in retro pixel art style, including UI. – Background music should be chiptune or 8-bit style. – Add sound effects for jumping, defeating enemies, and collecting items.

I want to create a 2D platformer game similar to Mario, but set in space. The player controls an astronaut. The game should have high jumps and low gravity. Platforms should be made of space rocks, space station parts, and asteroids. Enemies can be alien creatures or robots. The player should be able to defeat enemies by jumping on them. The goal is to reach the rocket ship at the end of the level while avoiding obstacles. The background should show a space scene. Include a simple scoring system and health (lives). Use retro pixel art style graphics.
