Space Impakto DS by relminator is an old school space shooter for Nintendo DS.

Changes:

Fixed the bug in the replay system interface
Changed the Replay System Interface to a more intuitive one.
Normal and Boss Rush has different highscore tables
Second loop!
Loop 2 is the “HARD MODE”(For HardCore BulletHell players) ala Strikers 1999 and Gunbird 2
Loop 2 is reminiscent of Psykyo 2nd loops where you kill something, it explodes bullets.
Level is also spawnign “popcorn” enemies when facing bosses to up the ante of difficulty.
Edited some enemy sequence to make the first loop beatable w/o using a single bomb.
