I managed to get just past 40 seconds after playing for about 5 mins (I am really bad at reflex stuff lol) so unfortunately didn't get to see the end.
What I liked: Fun mechanics, felt polished and fair and kept me wanting to play for a while. I liked the section where you had to run away from the rocks coming at you, that felt really fun. You also did a great job with the juice, the sound effects, shadows, particles all felt great.
Things to improve: Showing the time the player reached in the score screen would be good. If you wanted to play into the countdown theme more, you could maybe have some extra timers showing when projectiles were going to be spawned and have pickups or something to increase the time or something.
Felt fun to play, I might come back to finish it later.
