I'm not sure what I did honestly, but I think I misunderstood how to play. All I know is that monster definitely seemed to be getting faster as I got the hang of it.

Sorry I didn’t make a tutorial; I just thought people would read the description. I think that’s my mistake. Anyway, the thing is that sometimes one of the random phones starts ringing and it lights up with a white light, and you need to run up and turn it off before the timer at the top right runs out; otherwise, it will turn off the lights and kill you anyway. You also need to survive for the time shown at the top of the screen, and then you win. You can also sprint in the game.
I’m sorry I didn’t include a tutorial in the game itself, but in any case, I’m glad you did such a mini‑review of my game. I’ll try to do better in the next game jam.
