(Suggested modification for this challenge):
For this challenge, the goal is to find which levels can be solved without using
any of the Player-Assist Tools (PAT) which NeoLemmix offers. Since the platform has introduced a number of these, it's become more likely that levels written specifically for NeoLemmix will require them in order for the level to be solved.
Here's a list of the PAT which NeoLemmix offers. The challenge will be to play through the levels without using any of these - so, really, we're looking for which levels
absolutely require one or more of these to be used in order for it to be solvable:
Assign-Whilst-Paused (Pause by itself is allowed, but no assignments may be made whilst the game is paused)
Framestepping
Direction Select
Skill Shadows
Clear Physics Mode
Splat Ruler
Highlight Lemming
Skill Queuing
And of course, Replay mode
Since the original games were written for Amiga, which doesn't feature any of these (and doesn't allow skills to be assigned whilst the game is paused), it's safe to assume that all of these levels are possible.
So,
we're looking more at custom content for this challenge, and - even
more specifically - that which is made for NXLV (new formats).
I've attached custom settings which disable any of the above features which
can be disabled, and which uses the most minimal Hotkey layout; add these to your
NeoLemmix/settings directory [
BE SURE TO BACK UP YOUR EXISTING ONES FIRST]. Feel free to add hotkeys for skill selection, fast forward, exit/skip level, restart and other general interface stuff - the idea is that none of the above features should be assigned to a hotkey, to make it easier to resist using them.
Note that the username in the settings file is set to "Player-Assist Challenge"; you can either leave it as this if you wish your contribution to the challenge to remain anonymous, or you can rename it. You can also of course modify the graphics/audio and other general settings to your liking.
Please do not upload videos as verification unless the level is particularly challenging or interesting. Replays will be accepted as verification on a trust basis to avoid a situation where many videos are being uploaded needlessly - for the most part, if you say you solved the level without using PAT, we'll believe you! However, if there are any levels which are revealed to be particularly difficult to solve without PAT, then we may ask for a video verification as well.
Good luck, and enjoy the challenge!
