Congrats on creating your first (?) game! It's awesome to see people pick up Unity to create horror experiences and I hope you found the platform really effective and bringing out the atmosphere you were going for. I like the inclusion of a dialog UI as well as multiple environments for the player to navigate. I think working through a more responsive control scheme could be helpful - I thought it was a little odd having something other than the usual WASD movement scheme but I got used to it.
I hope you continue creating horror experiences and let your imagination go wild as you grow with proficiency in the Unity platform! I'd love to hear what ideas you'd like to created with this game as a WIP.
Thanks for submitting Horror Experience to the SCREAM LITE jam!
