Pretty cool game! Loved the use of sound effects on the title screen and game over screen, and the opening cutscene was very nice.
Regarding the gameplay, I was a bit confused at first as to why I kept on dying before I noticed that letting the ice rock counter thing hit the negatives seems to kill me. The black hole in the middle of the screen is cool, but I felt like it took up too much space, especially once it starts expanding, which makes things a little unmanageable.
Aside from those criticisms, had a fun time with this one. Good work!
Honestly, if staying in a time loop was what it took to have a cool codename like “Pigeon”…
