Here's some new features that weren't initially in the game but were influenced through the recent playtests.
- Awards system: Originally I hadn't planned for it, but it is great fun to have little extra challenges for which to strive in addition to "just beating the game" or a high score.
- Story paintings: I had a story in mind as I was creating the game initially but wasn't sure if it was going to fit the final game. Dean Dodrill suggested I add some story element to make the game feel "complete".
- 1UP super-bombs: Initially if you hit the 30 ship single-player max, the 1UPs just added to your score. Players wanted something more, so I decided the extra 1UPs could be triggered to act as super-bombs instead!
- More Bosses and monsters: I love making monsters. That shouldn't be a surprise after Weapon of Choice. But initially Shoot 1UP was going to be pretty small. It's not a giant game now, but it's definitely filled out, and so far everyone's really loving all the new bosses!
