I'm sorry, but you missed secret and tales.Secret Tales of Adventure Phantasy Saga. I mean, you can't be more generic, can you?
And generic is your plot. Dark dimension, an ancient evil sealed, yadda yadda. It can be done right. Really: I'm tired of games trying so hard so avert these tropes. I miss the old Evil-because-so (now the antagonist is always some misinterpreted dude) trying to destroy the universe because he wants.
I really like the idea of two endings, one being harder than the other.
Now, I can't answer your poll, because you asked if this interesting and original? And the answer is: Yes, it can be made really interesting but no, it is not original.
But as I said on my second paragraph, sometimes people try too much to be original.
It's definitely discouraging when streamers give a try-to-say-it-nicely (i.e. bad) review of your game demo. It's like jumping into a cold pool. Bad initally, but it gets better with time. And you are now more alert and see better.
Went to get some stuff for February 10, the birthday of my favorite ink monster...
I have a little one-person party for Bendy every year, complete with the life-size plushie I made. And yes, I bake a birthday cake!
