The focus on one game element that has several functions - as a single bullet, as a boomerang and as a pulse weapon - was really neat implemented and let you some space to focus on the polishment of the game. That was a wonderful thing! I'm glad you made this little game and I hope you'll create more such stuff in the future. :) I wrote a little article about it and also created a playthrough video - maybe it's interesting for some of your potential players. Keep up the good work!
Best wishes,
Sebastian
