Yes, it is the game I always wanted more of :P I'm trying to do my best to make this game truly my own, but I can't deny the inspiration for sure. Also, I'm glad you like it! There definitely will be more content... I have 10 Acts story boarded and Act 2 is arguably the smallest out of the remaining Acts. Once I get all the story fully mapped out (I'm at the beginning of Act 8 right now), I will resume making the Acts in the game itself.
Honestly, hearing you say that you have much more content (even if it's just a general direction where you want to go with it) gives me a lot of hope for this game to be a really fun experience. Part of the reason I have struggled to push through and finish Increlution is that the developer stopped updating, which makes me feel like I'm getting into the story for no reason.
