I really enjoyed that narrative and language for this game. i managed to complete it on the 3rd try! i appreciate the space between the turret bullets being just enough for me to slip by, and them fading out promptly.
i thought the health indicator was really clever, but maybe in an easier difficulty the recovery speed could be faster. i also like the look of the game, you wouldnt even expect that you were limited to 2 shapes (and pentagons Lol)
i did agree with 2 of the previous comments being that the bubble is too slow, and you might miss a pyramid, but these do contrast so its hard to find balance. perhaps if you choose to develop this further, difficulty modes could be an idea, or having more than the required amount of pyramids on the map. gg!
