Level 11, i entered the time machine at the same time as a past counterpart. It doesn't do anything anymore. the next counterpart didn't appear. thought the devs would like to know ._.
I got this AXE-cruciating bug you might want to look into. Wave 30, boss battle, I threw a grenade at him as he started throwing the axes. The axes glitched massively, all the frames of the axes' movements appeared at once, the SFX of the axe hitting the ground repeated itself as every axe touched the ground (every frame).
Thing is, this made it virtually impossible for me to dodge the axes.
Other than that very minor detail, since it only happened once, It was a great game. 5/5
After you turn off the light for the first time, there will be a smoker under a lamp and a door nearby, if you enter that door you'll go to a 2 story bathroom. How... uncouth that couple in the second floor. Lol
