Wow, so many questions!
Let's see...
Jonas, my project partner and I are using RPG Maker VX Ace to create the game. It is less code-heavy which allows us to focus more on the art and story of the experience.
Regarding gameplay, we are still debating if we should make it episodical or not. We are aiming at around 10-12 hours of exploration and fun... we just don't know yet if we should split those hours into more-polished separate episodes or not.
More episodes might also offer quick feedback which can help, in turn, making the following episodes better.
Monsters? Hmmm, not sure yet. Cooper wants zombie-furries in there, but I'd rather go with something spookier. We will definitely have SOME type of monsters, but maybe not as direct enemies.
Regarding multiple endings: Since the game acts like a "bridge" between our first book and the upcoming sequel (Trap Me 2), it might be tricky doing multiple endings. However, we'll take your suggestion into debate.
Thanks!
T-Yoshi45 (brilliant name), hopefully we will satisfy your curiosity in due time, with concept art and gameplay elements in the upcoming Developfur Diaries.
Shim, Lone Survivor was heavily influenced by Silent Hill 2. We also love SH2, so... in a way, yes, the graphical style will resemble that - we have the same inspirational material.
Now let us ask YOU: What don't you want to see in it? What things annoy you most or make you not wanna play a game? We're all ears.
