Dirgantara: First Phase (Unhacked Version)

Game Information
Blast your way through the game. Destroy everything. Let no one escape in this bullet-hell, single-level SHMUP. It's difficulty is rather high so least expect on finishing it on the first try. The enemies' pattern are fixed and synchronized to the song, so try to memorize the pattern, place the SLAVEs on the right place, find the efficient way to destroy their pattern. No bombs, no second try, skill + tactics only.
