I've seen videos of "Hello Neighbor" before and I think the concept is really exciting. If you're interested in sticking with this genre... I think there's still a gap in the market.
It's great to hear that you took the plunge and used a new engine. I try out new languages once a year, but I always end up going back to what I know.
Your game runs smoothly and was too easy for me, a pro gamer. :) Overall, a great project.
Well done!
