Nice short boss rush game! The first level is slow and boring with limited movement and shielded boss. However that turns out to be the most unique boss in this game since the remaining bosses are pretty much the same save their different shields.
Thanks! Originally, the goal was to have progressive difficulty, but I had to override that when I saw I was running out of time. The first level is based on a logical factor that implements the spin theme in a unique way. Thank you for rating and trying out my game! :)
