Space Impakto DS is a Bullet-Hell SHMUP (Space Shooter/Shoot'Em Up) with a devilish difficulty as the game progresses and 3D backgrounds.

It was presented in the GBAtemp Homebrew Bounty 2011 (DS, 1st place).

Features

• 2D gameplay.
• 3D background.
• Optimized texture use via texture packing.
• Oldskool 8-bit/4bit sprites.
• Newskool bullet hell gameplay.
• Source included (use and abuse license but give credit where it is due).
• Replay system.
• Button config.
• Varied and animated Bosses.
• Proceduraly generated backgrounds.
• Proceduraly generated 3d models.
• 3 types of ships.
• 2 Game Modes (Normal and Boss Rush).
• Auto-bomb (when autobomb is ON, you won't have bomb powerups at the end of the stage so "Pick Your Poison").

User guide

Shoot everything that moves. Try to destroy the boss as much as possible. There is a boss timer that will auto destroy the boss but you won't get a score bonus this way.

There is always a safe area no matter how crazy the patterns are.

About Replay:

• Only available after 1 game( doesn't matter if you loose or not) or...
• Also available when there is a saved replay on the flashcart.
• Not available when you return to the main menu when the game is paused.

Score should be a little higher with autobomb set to off. If all else fails, don't move!
