I don't know if you are trying to make this a serious game or not. like you wanna actually make a mascot horror game that ppl remember. If so, please consider making character models more appealing? Its definitely nothing eyecatching and something I'd WANT to remember, they look sort of just plain & boring. especially Fred. I'm not trying to discourage you, i want your success, but what made Bendy and Poppy so likeable (heck even the new My Friendly Neighborhood), was that their characters were neat looking and polished. (you can have funky looking characters but if characters are only remembered bc they are so funky looking, that doesn't make them appealing.)
I know its the demo, but from first impressions, unless you plan on something wholly different, the game world is pretty empty. I know alot of people are gonna say this is just riding off the coat tails of the other mascot horror successes, so I really hope you add more to do then just, note, puzzle and next area.
Collectables, good voice acting, rich lore and characters that aren't forgettable and just gross looking XD. Anyways, that was my take when playing this game! I hope for your success! (otherwise ppl are gonna do what they did for BANBAN and buy/refund) :/
\o/ hoping the full release goes well!
