Developer Notes:
[SPOILER]
The game is currently in ALPHA phase, and made on a custom engine, so bugs are to be expected.
The game is currently in DEMO phase, so don’t waste too much of your time, as there’s barely any content.
The game will contain Romance as one of it’s main routes, but it’s not just a romance game, it also contains avoidable NTR as a punish/playstyle mechanic.
If you want to play a good game and not Beta Test, you should wait until I remove the demo from the title, as I would’ve deemed the game worth playing at that time.

Summary

Project Novem is a sandbox management game, with a turn-based, combo-focused RPG combat. You take control of one of the generals of an organization,tasked to defeat a curse, which is on the fringe of wiping off humanity. This version a demo, with only the foundations of the game, so don’t waste too much of your time on it.
Development
  • The main games I’m using as reference are Nebelgeister and Karryn’s Prison.
  • But I’m also referencing Celesphonia and Pray Game for their general structure and events.
  • And Encode Encore! for the H System.
I’m going for a Full Romance Route, with Avoidable NTR as a punish/playstyle mechanic. As a sandbox game, the route you’ll end up getting will not only depend on how you play, but on how well and optimally you play as well, so no “A (NTR)” or  “B (Romance)”, your actions will affect 200 variables, and those will determine your route.
The scenes are made in koikatsu, mostly original, but some modified bepisdb scenes. I’ve been working on it since October 2024, and I’ll be sharing substantial progress every once in a while.
