Most should, if not all of them. There are things in the engine that we hard-code as opposed to reading them from the game assets, e.g. new animations cannot be added at the moment, but we'll sort it out. As a rule of thumb, mods that create or modify *assets* should work (this includes new areas and scripts). Anything that relies of less studied files, or fiddles with vanilla executables, will not.
Thanks!
Talking about possible - anything is, this is an open-source project after all. Do I have plans to add anything graphics wise? Not for the time being. I find it much more important to focus on the gameplay - particularly making the first game completable, minus the minigames.
Changing vanilla behaviour is kind of a grey area, but that certainly sounds doable. Things like these could work as a feature toggle, I think.
@sELFiNDUCEDcOMA @seedhartha If you two have anything else discuss about this off-topic matter, please either have it in an appropriate thread (as already noted by sic) or take it to PMs. Thanks to you both for your understanding!
