From a learning perspective

This game was made with the wonderful Pico-8 engine.

In this pico-8 source code you will find examples of:

- Cartridge data management : save/load scores and stats (dset/dget)

- Direct access to sprite/video memory : dynamically alter graphics when an enemy is hit (peek/poke/memcpy)

- Big sprite partially stretched (during title or game over screen)

To access to the source code you need to support by donating at least $1.99 USD.





- Inspired by the game Warning Forever -

Other references:

- Galaxian

- Gradius (for "Option" powerups)
