TriangleWingXXXX Steam CD Key

This is a STG game. Player need to switch back and forth in 7 modes to survive in the randomly generated enemies' attack. Firing bullets will cost normal energy or special energy. Normal energy can recover gradually and special Energy can only recover by firing in specified mode or dodging. When normal energy runs out, TriangleWing can not move or fire bullets for 3 seconds, and when special energy runs out, TriangleWing can not switch for 3 seconds. So it's fatal to run out of energy. ******
