Good game, altho I think the gameplay was missing something and the endings could have been worked more on.
but overall, I think it was a creative idea!
Gameplay:
As for the gameplay, I think it doesn't feel good but you have to repeat certain things over and over which will make the players tired, especially when it is fast passed and the player needs to react quickly.
Endings:
The first ending I watched the gameplay from the Markiplier video was a cool and creepy cinematic, but the second one was too similar and I think it made it boring. If you could make the second ending a bit more exciting it would have been so much better!
As a game developer, I understand how much effort it takes to make a game like this. I hope you could improve your game dev skills more with my feedback :)
