Unfortunately, I won't be able to support both modes at the same time. At least until the release. I miss some of the mechanics from the previous version, but some would be hard to balance properly - by the time I decided to drop that, there were new mechanics layering on top of the existing ones, trying to balance things - a time limit to prevent from getting lots of energy, negative effects on multiple EXMs installed to prevent from abusive builds that were breaking any need to get new EXMs and so on.
I kind of liked the time-limit but I would change it a bit. I really liked breaking things apart to get parts out of them. I liked transferring weapon parts back to have a better starting weapon. There were no side quests that would give you a massive amount of points which would counter the problem with optimising runs to get as much KP as possible. There are lots of things that could be improved to make it a bit complicated but fun and demanding experience. I'd like to develop the ideas from the previous loop but as either classic mode for TFG or as a completely separate game. If it would be a separate game, I would consider TFG something that introduces some basic concepts and that other game would be completely stripped off of any tutorials and explanations, making discovering things an experience on its own. I'd even consider dropping any words, keeping in just pictures, even abstract ones. Keeping it as DLC would be better as this would be a really niche experience but having it as a part of another game, could make it possible to get to people who would never consider trying it.
Hm. It's me that I already have ideas of what the game would be about and how hiding everything and leaving for the player to discover it, would fit the story.
Not now though. Right now, Tea For God is complicated enough to not be a plain shooter (unless you play with infinite ammo/health) but as easy as you could introduce mechanics in a few sentences (someone at the discord server did that :) ).
