Found an issue when I ran into the Krotite. after they murdered LI it restarted and dropped me to meager frames per second.
No idea what this could be, i've tested this situation a lot and never had that problem. Will investigate. Thanks for finding this one.
1. seems like you were trying to create a sort of hyper expert mode specifically for people that try to push themselves to gaming ridiculousness.
Not really, everything was test-played multiple times, by multiple people, and the difficulty adjusted based on the feedback.
E.g. if i'm able to get through without using food, everyone else should manage perfectly fine with food.
(But indeed there are adjustements to be made, see below.)
This makes it rather difficult for anyone jumping back in who identifies as a casual gamer.
Have you tried point & click games instead?
Oh and play meatymod, you'll love it.

2. The weight system IS the worst aspect of the mod [...]
After trying to deal with this system I highly disapprove of the mechanic.
This is still subject to debate. See, this is why we released a preview in the first place. To get feedback on things like this.
3: Adding late game enemies to early game areas: The Dev's didn't do so for a reason.
For example, where?
There are 2 places i remember where there are many normal and 1-2 harder enemies, but both places are designed that it is better to run instead of fight:
1) The room just before the long current in the bottom of the temple
2) The diagonal shaft with ekkrit in it.
But definitely no late-game ones...?
Anyway. Even if my reactions on irc may not seem like: Thanks for the feedback, and we'll see what we can do

EDIT: Followup:
Looks like we'll implement 3 or 4 difficulty levels, that influence things like spawn rate, inventory system (old vs new), AI, and various other things. Since it's kinda impossible to please everyone with a single, uniform difficulty, this is probably the most sensible thing to do.
EDIT2: i'll give this a shot and possibly update the release to include a difficuly switch. Might take a bit but could be worth it.
