Super fun game, loved the concept and had a really good time playing this! I think the main thing i liked was how the objectives are random, so there is enough variation in the gameplay . Some of the objectives are really difficult like staying in the moving pentagon :D but also a good thing to have some pacifist gameplay which is absent in most arena shooters so that was a relief! The use of the theme was also really creative and i think the overall balance was also well adjusted. Small suggestion i have would be to not make the player repeat the objectives which are already complete from the previous run.. i think this could make it even more fun!
Overall great job, really nicely done :)
