Me and one other person have been working on this for over 7 years, and it's finally done! You play as Boki, who can copy weapons from enemies and then combine up to 3 at a time. Blast robots in cyberspace and train to be a superhero! There's tons of bosses, a level editor, and an Endless Mode that goes through a few dozen environments. I'm super proud of this, so give it a shot!
