Someone, Call the SCP foundation!
This is a true Horror experience, the gameplay is very straightforward, but the atmosphere and the enverioment is very spooky . it's ingriguing the story. there is a monster on the loose and it's catching children and adults on this slide, taking them on some other dimension (it looks like an aztec pyramid) and (it's implied) feed other monsters like him.
my opinion:
call the scp foundation and cointaint it haha, i'll give it a 10/10, a true short horror game.
