Nice. I love this game. I enjoyed the "linking between bullets" mechanic along with simple ghosts, and some very very nice particle effects (good indication where the enemy spawns, dies, and bullet particles too. Imo, the red cursor line is a nice touch to make the game screen a bit less empty, but not too clustered.)
The sound effects can stack up, making it a bit loud, though.
This game is very fun to play.
