This is my First PICO 8 project, Sphere buster.

It plays just like asteroids, press left or right to turn the ship, press Z to thrust, X to shoot, and hold down to activate shield.

you must destroy all enemies on the screen including spheres, saucers, and magnet missiles. after the regular wave, a bonus wave starts where you destroy blue aliens, get 3 different weapon power ups and shield recharger, and can't wrap around the screen. If you die in this wave, you automically pass to the next regular wave.

Every 5th wave features giant spheres.

you get a bonus life after every 1000 points.

Some tips :

  • Yellow saucers are deadly, especially after 5000 points. Move the ship and activate the shield wisely to survive.

  • manually pressing X is faster than holding to fire.

  • the shield's energy decreases when the shield is collided with enemies or absorbed bullets. you can't use shield if the energy ran out.

Any feedbacks are welcome!

1.1 update:

  • saucers won't spawn on other ememies and die instantly.

  • increased blue aliens' movement speed a bit.

1.2 update

it seems the final difficulty level was way too hard so I made it easier.

  • Max number of spheres is 9 instead of 10.

  • now only one saucers will spawn at once, 2 were too hard to deal with.

  • decreased blue aliens' speed.

You've got my star.
Simply superb ! One of my all-time favorite shooters for Pico-8 now, based upon the original arcade "Asteroids Deluxe" I believe.

thanks dw817!

1.3 update:

  • laser seemed to be too op and 3 way is too underpowered, so I nerfed and buffed their effective range.

  • Added sound effects when the enemies or bullets are collided with shield.

  • Magnet missile won't spawn when there are more than 14 enemies on the screen to prevent slowdown.

This is pretty much the final version, I'll work on the next project now.
