Development in unity will take time as is any game. I just hope you guys have a good plan for it. Grab-type does fit the bill for what you're going for with the demo so far. One other suggestion but for saving the game if it is considered. Lighting a Candle to signify safety. I take it that with the grabs they'll try to haul off your stuff but something fun to consider for the ghosts would be possession. With salt being a means to shake them off immediately. Either way I look forward to what you and your crew come up with. I just hope you guys don't get hit with that scope creep. But if there was one additional thing to give feedback on, it would have to be smoothness in the movement. As it is right now, it's fine but I hope you can optimize the player movements a little better. the speed was not too much of an issue but the way the camera moved was stiff as was the transitions between the stairs. Best of luck to you and your team. I'll be looking forward to the future development of this game.
