Having a really hard time with the struggling, haven't been able to struggle out at all (except the friendly worm at the start). Part of the problem is I don't know where keys are by name while in WASD position - most games tend to use directional inputs ("right") instead (plus this translates well to gamepads). So I spend a bunch of time thinking "wait, which one is S, again?"
Even with the Player Struggle Multiplier set to 3.5 I still can't get out consistently.
Also some indicator (visual? audio?) for correct button presses and out-of-stamina presses would be nice.
Hoping you keep at it, will be following this project!
