The intention is for it to flow like the old school single player levels of Doom and Quake where you have monsters and puzzles and your goal is to reach the exit. SO in some ways it will play like a roguelike in that you have one chance to beat the level. It will feel different in that you build up points by playing and beating the levels over and over again which give you access to harder difficulties and harder levels. So the progress will have a much higher degree of risk vs reward and you will always be on edge when it comes to taking damage because your rewards at the end of the map are reflected in your performance and map completion.
The single player will come after I make the multiplayer duel mode as the monster AI and models will take a lot of effort.
There’s some really good potential for interesting game-play here. I really like that you can only have a weapon for 30 seconds at at time. You can do some very neat design choices to bring out the action and providing a good challenge to the player.
