For anyone playing, the power ups are:
- Extra Shield
- Figure 8 floating skull
- Add smiley, they auto attack
- ? (Extra speed or faster rotation)
- Full HP
There is no ending, waves get bigger over time.
I usually take a full month to make a game for JS13K, I only worked on this a few hours each night, my main goal was to make a full game that worked on mobile and PC. Spent a lot of time on character select and menu and neglected the comabt. I liked the concept but it needs some work!
