Exolon DX (Windows game 2005)

Exolon DX is a remake game remade by Retrospec Presents. The original game was made by Hewson Consultants and released for Amiga, Amstrad CPC, Atari ST, Commodore 64, Enterprise 128, ZX Spectrum. The genre of the game is run ’n’ gun (run and gun) or platform. I think that it’s so hard. Because the game main character dies easily and it has no any lives. Besides, colored bubble enemy units appear from the right side suddenly.
