I appreciate your feedback. Thanks for checking it out despite the rough state it was in.
I don't know if I'll revisit or improve on this specific game, but I'll be sure to use what I learned from making it on other projects going forward.
FNAF is the best known game made with Clickteam Fusion. I would say that as an engine it is about as versatile as Gamemaker Studio, but a little bit easier to learn (for me anyways, learning curves are at least a little bit subjective.)
