Game Review Time
What I liked
The game respected the theme quite well, and I found the general idea of slowly snow balling out of control to be relatively funny; I now get the thumb nail. I also thought the weapon variety and ship variety you come across to be quite good.
What I didn't like and how to address them.
There are a few accessibility issues with the game. The actual movement got quite dizzying when doing hard turns for example. I would recommend playing around and learning how to use something like CineMachine as it helps out quite a lot for short time scale projects. For future jams I would highly recommend working on getting the game exported to WebGL, that way you worry a lot less about people being unable to play your game due to OS, and you don't get caught up in virus paranoia. I wasn't sure where my core was, so whilst I understood that missiles could hit me, I didn't understand what did and did not take damage when I was being shot at.
Potential Improvements
Whilst you had music and pretty good music that looped seamlessly without getting too repetitive; the sound effects were somewhat lacking.
Overall Thoughts
Overall, this was quite a nice little game with a very good idea at its core. Great job!
