Yes, I put that in the description; I wasn't trying to hide that. I built this for a 48 hour game jam. I wanted to learn how to make a vertical scrolling. I did the tutorial for the first day and added shields, pick ups, limited ammo, changed thr music and some sound fx, added a story line, dialog pop ups, and a combo meter in the next day. I think you get the point that it's diffrent, but the base mechanics would be the same anyway and if i had changed the are you would have never know. Thanks for checking out my game and go check out heartbeast's channel and show him some love.
