Wow, thank you a lot for the amount of constructive feedback!
Sorry for the jumpscare, I just didn't know what to add in the end if you win ahah. The missing sound is my fault, I just didnt allocate some time to find a sound designer when it was perfectly possible to find one. The keys are the last feature. At first, I thought about having different "victims" but due to time I couldn't add that form of progression (just a text appearing saying "victim nº1",etc..). The hard knock is a really cool idea! I might add it. But the ghost is not programmed to find you, just go around. Thank you once again.
