This is a very impressive entry! I would happily pay full price that looks and sounds as good as this does!
The gameplay itself was a little bit frustrating. Platforming challenges in first person are tough, but the bottomless pit makes them very unforgiving. When stage 3 began, a pulsating black cube appeared in my field of view in seconds, and I was dead before I could recognize that it was an enemy or shoot it. I would have happily tried again, but I found myself back on stage 1.
I really did appreciate the world-building on display here though. The multiverse training mission is a cute take on the theme, and I loved the little touches like the recruitment poster in the lobby and the instructional voiceover.
